Amit Kumar Jain Abstract— Presently the world has enormous advancement in science and technology the topic considered here is just a drop out of an ocean of knowledge. Higher product quality, better reliability, better availability of plants, optimization of cost and efficient working of boilers is the chief concern now a days. Generally the production can be increased by the efficient use of b...

Combustion mechanism of a 300 MW pulverized coal boiler is analyzed and the optimization of the performance of the boiler is carried out. The flow field, temperature field, devolatilization, char combustion and CO generation in the boiler furnace under actual condition is obtained by using Fluent. Three methods to improve the efficiency of boiler combustion are proposed based on the pulverized ...

The last fifteen years many European countries have integrated large percentage of renewable energy on their electricity generation mix. In Denmark the 21.3% of the electricity consumed nowadays is produced by the wind, and it has planned to be the 50% by 2025. In order to front future challenges on the power system control and operation, created by this unstable way of generation, Demand Side ...

AbstractDeaerator is normally used in Chemical Industries, Process Industries, Power Plants and in Paper and Pulp Industries. The oxygen in the boiler feed water is the main reason of boiler corrosion. Oxygen corrosion is one of the biggest dangers of boiler. The function of the deaerator is to remove the dissolved oxygen from the boiler feed water before entering into boiler .The removal of di...

Fe-2.25Cr-1Mo a widely used material for headers and steam tubes of boilers. Welding of steam tube to header is required for production of boiler. Heat affected zone of the weld can have poor mechanical properties and poor corrosion behavior leading to weld failure. The cost of material used for steam tube and header of boiler should be controlled. This study propose a new materials design for ...

The impact of different energy storages on power systems has become more important due to the development of energy storage technologies. This paper optimizes the stochastic scheduling of a wind-based multiple energy system (MES) and evaluates the operation of the proposed system in combination with electrical and thermal demand-response programs and the three-mode CAES (TM-CAES) unit. The prop...

NOx emission characteristics and overall heat loss model for a 300MW coal-fired boiler were established by Back Propagation (BP) neural network, by which the the functional relationship between outputs (NOx emissions & overall heat loss of the boiler) and inputs (operational parameters of the boiler) of a coal-fired boiler can be predicted. A number of field test data from a full-scale operatin...

The economizers are used for production of steam heating on en route ships. The economizers are producing steam in a heat exchange process from the ship’s main engine exhaust gas. Products of the incomplete combustion of the heavy fuel oil remaining in engines, passing the boiler, collect on the heat exchange surface of the economizer. When the incorrect assumptions are made for the boiler oper...

All tea plants in India rely on the national grid for their electrical needs and diesel thermal energy transportation, which are encountering high costs, emissions, issues of accessibility. In this paper, hybrid renewable systems based both standalone grid-connected technologies have been modeled using HOMER Pro software supplying power to a manufacturing plant typical rural area India, namely,...
