Abstract:
This paper focuses on indirect biomass drying. It compares the operating characteristics of a laboratory-scale drum dryer and a pilot-scale rotary dryer. Before the design of an industrial dryer for a specific material, it is important to experimentally prove the process and to determine the drying characteristics of the material. To verify the portability of experimental results for indirect dryers, a drum dryer with indirect electric heating in a laboratory scale was designed and built to test and study the process of indirect drying. Based on the results obtained on a small-scale device, a prototype of a pilot steam-heated rotary dryer was designed and manufactured. A broad range of experiments with green wood chips and wet bark from open-air storage with moisture contents of 50 to 65 wt % were carried out on both dryers. The drying curves indicating the process, the square and volumetric evaporation capacities, and the drying energy consumption were obtained and compared, and the feasibility of indirect drying for these tested types of biomass was confirmed.

Abstract:
Abstract A mathematical model for the rotary dryer that determines the total residence time is developed. Experiments were performed in a laboratory-scale direct contact rotary dryer with the gas flowing concurrently with the solids. The model predictions depicted that the total residence time decreases with increasing the inclination of the rotary drum, the speed of rotation and the radius of rotary drum. The validation of the model was carried out experimentally for maize while varying the inclination of the rotary drum and the speed of rotation. The experimental results were observed to be in good agreement with the model predictions.

Abstract:
This article investigates the effect of the filling ratio of the indirect rotary dryers on their operating characteristics. For moist biomass drying before combustion, the use of indirect drum dryers heated by a low pressure steam has proven to be highly suitable. Regarding the design of new dryers, it is necessary to experimentally verify the operating characteristics for specific materials and drying conditions. For this purpose, a set of experiments on a steam heated rotary drum dryer were carried out with green wood chips containing 60 to 66 wt% of moisture. The following operational characteristics of the dryer were experimentally determined: drying curves describing the process, square and volumetric evaporation capacities and drying heat consumptions. Based on the experimental results, the effect of various drum filling by dried material on the mentioned operating characteristics was analysed. On the one hand, higher drum filling ratio increases the drying time, on the other hand, the evaporation capacity also increases, while the specific energy consumption does not significantly alter. The maximum value of the evaporation capacity was reached when the drum was filled to 20 wt%. When the filling ratio was increased to 25 wt%, the evaporation capacity experienced almost no change.

PLC has system to regulate the movement of machine components, displacement system of product, system settings motion or displacement of other components. PLC is a control system with some advantages such as simple in design, easy to use and circuit modification, low cost, easy maintenance, high reliability and safe. In this paper, we will focus on the PLC that used in the control of equipment movement on the rotary dryer system for waste liquid processing. PLC will be control the movement of the motor for drum of dryer, heating system, water circulation in the wet scrubber system, vacuum cleaner and smoke systems. All these systems are connected by PLC and working by arranged the setting time of system. The first process, PLC will activate the motion system of motor to drive the dryer drum rotating to left or right side. Then the burner is active for heating the drum of dryer. Effect in this process made smoke and dust happen in the rotary dryer system. The pump automatically will be activating to spray water on a wet scrubber system to catch the dust and smoke. Dust and smoke will be inhaled by the blower and flow back into the rotary dryer machine. Therefore there is no smoke and dust flowing into the environment. The results show that the PLC can be control the motion system and processes machine rotary dryer to drying the waste liquid in short time. Such as 20 minutes to 5 liters of liquid waste volume and 30 minutes to 15 liters and made the waste liquid be friendly environment.

Abstract:
In this study, a new type of rotary dryer filled with inert alumina ceramic bead (ACB) fillers was introduced to treat the industrial wastewater, e.g., the high-salt wastewater and landfill leachate. Numerical simulations based on the Discrete Element Method (DEM) on the motion trajectory of ACB fillers in the rotary dryer were conducted, and the parameters of flight structure, rotational speed, and filling degree on the dynamic behavior of ACB fillers were optimized. Under various rotational speeds and filling degrees, the experimental results fit the numerical-simulated results very well. The optimized flight configuration was the straight flights with a length of 65 mm, and the optimized rotational speed and filling degree were 35 rpm and 15%, respectively. Under the optimized condition, both the response variables, the mass of particles in the airborne phase (MAP) and the percentage of occupied area in the airborne region (OAR), have the optimal values, in which the dryer will have a better drying performance. Besides, the lower-right area of the drum is empty which is convenient for the installation of the inlet pipe. The drying experiments of industrial wastewaters were also studied using this ACB filled rotary drum dryer under the optimized conditions. Under the optimal operational conditions, the evaporation capacities of the high-salt wastewater and landfill leachate could reach as high as 49.7 kg/h and 90 kg/h, respectively. This study highlights the integration of evaporation and drying processes of this novel ACB filled rotary dryer and provides an efficient and zero-liquid-emission strategy for the thermal treatment of industrial wastewater.

The purpose of this research was to investigate the drum rotary dryer for pangola grass drying. The forage variety used was pangola grass A254. The objectives of this study were to elucidate the characteristics of this specific drum rotary dryer. The drying machine is consisted of burner, dryer, blower, cyclone, convey or et al. Experiments were proceeded according to the characteristics of the machine. The operating parameters were feed rate, particle size and excess air. Besides the drying efficiency and collection efficiency of pangola grass, analysis were carried out on the composition of crude protein, crude fat, crude fiber and trace elements of Phosphorus, Potassium, Calcium, as well as ash content of panagola grass after drying. The primary objective was set at improving the operating efficiency of this drying machine. The results showed that drying efficiency could be enhanced, if the panagola grass was pre-cut. Moreover it can increase the drying efficiency and avoid the forage clogging in the drying machine. The optimum conditions found that air velocity is about 7.1~8.3 m/s, panagola grass size 6 cm, and feed rate 10 kg/min. There was no significant difference on the approximate compositions when compared with used solar drying. It shows the potential of applying machine drying in replacing solar drying.

Abstract:
This paper discusses the retrofit injection of humid gas from sludge dryer with secondary air in the WTE furnaces in Que´bec City. In 1992, a municipal sludge treatment plant was added in the WTE building. Three sludge dryers, each connected to a furnace, were added. Direct contact with hot furnace gas was used to dry sludge in a rotary drum. Humid gas from the dryer was returned to the rear wall of the furnace just above the finishing grate. CFD modeling showed cold flow of humid gas on the rear furnace wall, restriction of the combustion area on the principal grate, and stratification of the flow inside the boiler. A retrofit of the first chamber of the boiler was designed using injection of humid gas from the sludge dryer with secondary air on the front and rear walls. The main purpose of the retrofit was to maintain CO levels of under 57 mg/m3 on a 4 hour mobile average. The first boiler was retrofitted in winter 2008 and results have been very encouraging.

Abstract:
The U.S. Department of Energy (DOE) and CH2M Hill Plateau Remediation Company (CHPRC) are seeking a waste treatment solution for sludge stored in the K-Basin spent fuel pond at the Hanford Nuclear Site, in Washington State, USA. This sludge is a Remote Handled Transuranic (RHTRU) waste destined for final disposal at the Waste Isolation Pilot Pant (WIPP) in New Mexico. Removal of the sludge from the K-Basin and transport for interim storage at the Hanford Site is referred to as Phase 1 in this process. Phase 2 is defined as the treatment and packaging of the sludge such that it can be transported and disposed at the WIPP. This paper discusses work in support of Phase 2. ISI’s GeoMelt ICV process is ideally suited to treating a heterogeneous sludge that is rich in uranium metal and which contains a mixture of other fuel derived products, earthen materials, and miscellaneous items (operational debris, resin, etc). GeoMelt can quickly and efficiently treat small drum load batches and will fully destroy organics, oxidize reactive metals, and permanently immobilize radioactive constituents within a high-integrity vitrified product that will meet or exceed all WIPP acceptance criteria. The GeoMelt Technology has an extensive experience base, having treated more waste by vitrification than any other company in the world (25,500 metric tons). The equipment tested for this Project phase constituted the front end, or Sludge Pretreatment and Transport steps, of the proposed GeoMelt process. These components first focused on an engineering scale (22-liter), followed by testing with a full-scale (130-liter), horizontal rotary plow dryer/mixer. The dryer removes water from the sludge, via external heating and under reduced pressure, and mixes it with glass forming minerals (GFM) prior to treatment in the GeoMelt ICV system. Testing was first performed in July and September 2010 using a 22-liter drying system, which demonstrated a baseline drying technique and allowed an assessment of the resulting physical properties before, during, and after drying/mixing. Full-scale testing using a 130-liter dryer and condensate system was then performed in October 2010. An Operational Acceptance Test (OAT) of the equipment, followed by four “Dryer Holdup” tests and three “GFM Cleanout” tests were performed. Each of the Project Test Objectives was successfully met. Both the 22-liter engineering-scale and the 130-liter full-scale steam jacketed, horizontal plow, dryer are shown to dry and mix 5-vol% solids K-Basin sludge and GFM without difficulty. These test results, combined with previous treatability testing in 2004 wherein successful GeoMelt vitrification of a K-Basin sludge simulant was demonstrated, confirm the efficacy of the overall treatment process towards providing an immediate solution to the final disposition of K Basin Sludge.
