5MW Coal Gasification Power Generation Plant
The basic principle of coal gasification system is to convert coal into combustible gas. It is then used as fuel in gas engine to generate electricity. Coal gasification system is characteristic of small land requirement and environment friendly.
Our coal gasification process includes three steps. The First step is coal gasification, which convert coal into syngas. The Second step is syngas purification. The producer gas coming from gasifier usually contains contaminants including dust, coke, tar and etc. The contaminants will be removed by the purification system to ensure normal operation of gas engine. The Third step is power generating in gas engine. The high temperature exhaust gas may be reused by waste heat boiler to generate steam or hot water for civil or industrial use). Steam turbine may also be considered to make a gas-steam combined cycle power plant, which will increase the total efficiency.
This technology uses thermochemistry conversion method. With company independent R&D technology, coal can be converted into electricity, heating or charcoal. Moreover, the coal can be turned into wealth and can be made full use of.
The basic principle of coal gasification power generation system is to convert the different types coal into gas, and use the combustible gas to drive gas generating equipment for electricity. It can take full advantage of the equipment's compact-design and environmental-friendly features. Therefore, it is one of the most eco-friendly way for coal.
The process of coal gasification power generation includes three steps. The first step is coal gasification. The coal is converted into combustible gas. The second step is gas purification. The gas has impurities through gasification, including ash, tar, which should be removed with purification system in order to ensure the operation of gas power generator. The third step is gas power generation, which use gas engines(spark plug ignition type) for electricity generation, and the high temperature flue gas produced by the gas engine can heat boiler to get steam or hot water for residential or industrial use.
The coal gasification power generation system adopts modular design, which can be normally applied to power stations of 50-20000KW.
