Abstract:

This paper presents a boiler efficiency analysis of a 220MW steam power plant using the direct method. The procedure employed to determine the boiler efficiency was done using the input-output method based on ASME PTC 4.1 standard. The experimental data used for the analysis were obtained from boilers installed in Egbin Thermal Power Plant located at Ikorodu, Lagos, Nigeria. Instantaneous data on boiler thermal efficiency can determine the condition of boiler operation, heat generation, and heat loss. It was established that boilers#-1, 2, 4, 5, and 6 have 72.51%, 67.66%, 69.50%, 78.16%, and 7

Abstract:

A boiler is a pressurized vessel utilized for the production of high-temperature steam. An often-encountered problem in boiler systems is the inefficiency of the working system, especially in fire tube boilers where heat loss occurs in the steam and fuel systems, leading to a decrease in efficiency. Hence, it is imperative to compute the efficiency of fire tube boilers in order to comply with efficiency regulations in operational procedures in the field. This study utilizes indirect methods to calculate efficiency. The calculation results indicate that the boiler efficiency, determined using t

Abstract:

A thermal energy is one of the most significant sources of environmental impact.This is a consequence of both the use of mostly non-renewable natural resources and environmental pollution from thermal power plants. The intensity of this impact depends on many factors, namely the purpose, power, type of fuel used and operating mode. Existing studies have established links between emissions and characteristics such as power and fuel type for stationary operating conditions. At the same time, changes in operating conditions have a significant impact on environmental and economic characteristics.

For this purpose, a baseline and goal line model of energy consumption as a function of steam production for an operational base period was constructed. The study shows that the steam generation process has a consumption rate of 0.0885 m3/kg, which

Increasing energy efficiency in the cement production process at PT Semen Padang is carried out by reusing exhaust gas to produce electricity using Waste heat recovery power generation (WHRPG) with a capacity of 8.5 MW. WHRPG is a technology for utilizing exhaust gas heat as a source of heat energy to heat feed water into steam by using a suspension preheater (SP) boiler and air quenching cooler (AQC) boiler. This study aims to calculate the power potential of the steam heat influenced by the steam temperature and the mass flow rate of the steam produced by the boiler, to calculate the efficie

Sustainability and efficient use of resources are becoming increasingly important aspects in the operation of all industries. Recently, some biomass-fired boilers have been equipped with increasingly complex condensing back-end heat recovery solutions, sometimes also using heat pumps to upgrade the low-grade heat. In kraft recovery boilers, however, scrubbers are still mainly for gas cleaning, with only simple heat recovery solutions. In this paper, we use process simulation software to study the potential to improve the power generation and energy efficiency by applying condensing back-end he

Abstract:

Boiler efficiency is called to some extent of total thermal energy which can be recovered from the fuel. Boiler efficiency losses are due to four major factors: Dry gas flux, the latent heat of steam in the flue gas, the combustion loss or the loss of unburned fuel, and radiation and convection losses. In this research, the thermal behavior of boilers in gas refinery facilities is studied and their efficiency and their losses are calculated. The main part of this research is comprised of analyzing the effect of various parameters on efficiency such as excess air, fuel moisture, air humidity, f
