Palm oil production process, there are a lot of biomass by-products, such as: palm empty fruit bunches, palm tree branches and leaves, palm shells, palm fiber, etc., you can effectively use the above biomass by-products as steam boiler fuel, using steam-driven turbine generator will be converted from biomass to electricity.
Effective utilization of biomass not only reduces the pollution of the environment, but also produces electricity can produce economic benefits and national standard of living, is currently one of the many countries to promote the direction of green energy.
The main processes for biomass power generation are:
The main equipment are: biomass crusher, biomass dryer, conveyor, water treatment system, steam boiler, turbine generator and so on.
Our company has been committed to the development of palm oil industry for a long time, and each large-scale palm oil crushing plant is equipped with its own biomass power generation facilities to realize the comprehensive economic benefits of self-sufficiency in electricity and domestic and exported electricity.
The main power stations are: 3MV/hour, 7.5MW/hour, 10MW/hour, 15MW/hour, 15MW/hour, 20MW/hour, 30MW/hour, 40MW/hour
Biomass feedstock, due to its large size, needs to be crushed in order to increase the combustion rate. In order to improve the combustion rate, the biomass needs to be crushed and processed so that it can meet the size requirements of steam boilers. A lot of biomass moisture is high, after crushing and drying, so that its moisture is reduced to ≤ 25%, more conducive to the full combustion of fuels.
Biomass boiler is to heat the water to a certain temperature and pressure state, so that it has enough power to drive the steam turbine. In order to improve the efficiency and life of the boiler need to boiler water softening treatment, RO osmosis reverse osmosis treatment, for special water quality using more stringent water treatment, the purpose of reducing the water Ca +, Mg +, O2 and other components.
A steam boiler heats water to produce steam at the rated temperature and pressure required by the turbine. Biomass has a relatively low ash melting point, which has special requirements for the fuel feed rate and the slagging method of the grate. Usually we use chain reciprocating grate and water-cooled vibrating grate.
Boiler steam after steam-water separation of steam into the steam turbine, the steam turbine to be maintained in a vacuum working environment, the selection of the turbine can be selected according to the production process and product characteristics, mainly condensing turbine generator, pumping turbine generator, back-pressure turbine generator.
The exhaust gas from the boiler has high temperature and dust, and heat exchange of the exhaust gas to heat the boiler water and air can effectively improve the thermal efficiency of the boiler. The dust in the tail gas is reduced by using bag filters and spraying method to reduce the tiny particulate matter in the tail gas.
