Embodiment 1
[0037] Example 1 of the present invention is as figure 1 As shown in Figure 3, the present invention can be promoted and applied by cooperating with large-scale rice factories to build power plants or building biomass power plants in grain production bases. The scale of power plants can be selected according to the local biomass resources. Generally, there are two types of 5MW and 10MW. specification.
[0038] The biomass energy power generation process of this embodiment includes the following steps:
[0039] (1) The biomass raw materials are processed, such as crushing plant straw raw materials, and the chaff raw materials can be used directly, and then the biomass raw materials are gasified, that is, the solid biomass is converted into combustible gas. The main components of these combustible gases Ingredients are CO, H 2 , CH 4 , CO 2 Etc., the gasified gas also contains certain impurities, such as ash, coke, a small amount of tar, etc.; after dust removal, coke removal and p...
Embodiment 2
[0046] Example 2 of the present invention is as Figure 4 As shown in ~7, the difference from the previous embodiment is that in the process of biomass power generation, in step 2, the high-temperature gas waste heat at the outlet of the gasifier 11 is first sent to the heat exchanger 18 to produce soda The steam-water mixture is then sent to the waste heat boiler 9 or the steam boiler 21, or sent to the waste heat boiler 9 and the steam boiler 21 for combustion to further generate superheated steam, and then transfer to step 3 to promote the steam turbine generator set to generate electricity;
[0047] In step 2, the dry ash generated after gasification of the biomass raw material and the wet ash generated after purification of the combustible gas are mixed first, and then sent to the steam boiler 21 for combustion;
[0048] In step 2, when necessary, the biomass raw material and ash are mixed and burned directly in the steam boiler 21 to generate superheated steam;
