Abstract:

The calorific value of coal gangue is an important indicator to assess its quality for comprehensive utilizations. Although the heating values can be measured experimentally with a Bomb calorimeter, an easier and faster approach within an acceptable tolerance is in great demand. Herein, we use an alternative approach to estimate the heating value based on proximate analysis data, which are measured under the instruction of GB/T 212-2008. The lower heating values of coal gangue samples we collected range from 2307 to 8309 kJ/kg, which are key information for the use of coal gangue in principle.

Abstract:

In this research, experimental samples were from Maoming, Huadian, Wangqing, Fushun and Longkou regions in different layers and different mining area. The experimental results of oil shale proximate analysis and heating value measurement show that there are certain relations between proximate analysis of moisture, ash, fixed carbon, volatile matter and lower heating value. The relations between oil shale lower heating value and proximate analysis have important significance to estimate the average characteristics of oil shale as received and oil shale combustion conditions in boiler.

Abstract:

Chlorella samples were pyrolysed in a fixed bed reactor with γ-Al2O3 or ZSM-5 molecular sieve catalyst at 600°C. Liquid oil samples was collected from pyrolysis experiments in a condenser and characterized for water content, kinematic viscosity and heating value. In the presence of catalysts , gas yield decreased and liquid yield increased when compared with non-catalytic pyrolysis at the same temperatures. Moreover, pyrolysis oil from catalytic with γ-Al2O3 runs carries lower water content and lower viscosity and higher heating value. Comparison of two catalytic products, the results were sho

Abstract:

Purpose – The purpose of this paper is to develop a barrel heating system using induction heating instead of resistance heating. And, a working coil for the induction heating system was designed so that the barrel has uniform temperature distribution. Design/methodology/approach – A coupling design combining the pitch of turns of working coil with the magnetic flux concentrators in the barrel induction heating system was developed to achieve uniform temperature distribution which was approximately the same as temperature uniformity obtained from that of resistance heating system. Findings – In

Abstract:

Municipal sludge waste combustion was studied by thermogravimetry (TG) and differential thermal analysis (DTA), to better understand the two main stages which occur during the combustion process, and to evaluate how much of the total and significant generated heat is released is during each combustion stage. A method to measure the lower heating value (LHV) on a dried basis was developed from the TG/DTA data and it was applied to the whole process and to each combustion stage. Chemical analysis of the residual products after each step shows that nitrogen organic compounds are burnt only from 3

Abstract:

Biomass is one of the most promising renewable energy sources because it enables energy accumulation and controlled production. With this, however, the demand for biofuels grows and thus there is an effort to expand their portfolio. Nevertheless, to use a broader range of biofuels, it is necessary to know their fuel properties, such as coarse and elemental analysis, or lower heating value. This paper presents the results of testing the fuel properties of several new, potentially usable biofuels, such as quinoa, camelina, crambe, and safflower, which are compared with some traditional biofuels

Abstract:

The focus of this work is to present the feasibility of lowering the supply and return temperatures of district heating networks in order to achieve energy savings through the implementation of feed-forward model predictive control. The current level of district heating technology dictates a need for higher supply temperatures, which is not the case when considering the future outlook. In part, this can be attributed to the fact that current networks are being controlled by operator experience and outdoor temperatures. The prospects of reducing network temperatures can be evaluated by developi

Abstract. Vertical structures of aerosol single scattering albedo (SSA), from near the surface through the free troposphere, have been estimated for the first time at distinct geographical locations over the Indian mainland and adjoining oceans, using in situ measurements of aerosol scattering and absorption coefficients aboard the Facility for Airborne Atmospheric Measurements (FAAM) BAe-146 aircraft during the South West Asian Aerosol Monsoon Interactions (SWAAMI) campaign from June to July 2016. These are used to examine the spatial variation of SSA profiles and also to characterize its tra

Abstract:

The induction heating process of slab steel had been discussed by finite element method. The results obtained were in good agreement to the measured value. In addition, the low-frequency induction heating process of slab steel was investigated and analyzed in detail according to the practice requirements of a steel mill. During the heating process of slab steel by low-frequency induction, the temperature increasing speed of surface is faster than that of center in initial time. With the increment of heating time, the temperature increasing speed of surface becomes lower because of the heat los

Abstract:

Abstract The composition of sewage sludge and, thus, its energetic potential is influenced by wastewater and wastewater treatment processes. Higher or lower heating values (HHV or LHV) are decisive factors for the incineration/gasification/pyrolysis of sewage sludge. The HHV is analyzed with a bomb calorimeter and converted to the LHV. It is also possible to calculate the heating value via chemical oxygen demand (COD), total volatile solids (TVS), and elemental composition. Calculating the LHV via the COD provides a suitable method. In contrast, the correlation of the HHV or LHV with the TVS i
