Embodiment 1

[0026] Reference attached figure 1 The present invention is further explained. The present invention is a biomass combustion power generation device. The biomass combustion power generation device includes a biomass burner (8), a thermoelectric engine (17), a cooler (24), a circulating pump (25), and a generator (26), The main components of the power control system (27). In addition, it also includes an air preheater (4) and a heat exchanger (20). Depending on the biomass material used, auxiliary devices such as a dust filter system (22) can also be installed. The following uses biomass pellets and briquette fuel to illustrate the working process of the device.

[0027] The biomass fuel (9) is put into the fuel bin of the biomass burner (8), pushed into the combustion chamber (10) by the screw feeder, and mixed with the primary combustion air (6) in the combustion chamber for combustion, Because the primary combustion air has a positive pressure, the flame formed by combustion ...

Embodiment 2

[0034] The principle of this example is basically the same as that of the first embodiment. The difference is that the biomass burner used in this embodiment is a gas biomass burner, and the biomass raw material is a combustible gas such as biogas. The heat generated by the combustion of these combustible gases drives the operation of the entire system.

[0035] The second embodiment can be used in pig farms, chicken farms and other breeding companies or in landfills, sewage treatment plants and other units. It can use animal manure or garbage to ferment to generate biogas, and then use a biogas biomass burner to drive the entire system operation Power generation can provide power support for feed crushing equipment, feed mixing equipment, feed conveying equipment, ventilation equipment, lighting equipment, heating equipment, and other electrical equipment in aquaculture enterprises, reducing enterprise costs.

Embodiment 3

[0037] The principle of this embodiment is basically the same as that of the first embodiment. The difference is that the biomass fuel used in this example is directly pulverized agricultural straw or forestry waste, and the directly pulverized biomass material is sent to be burned through a hydraulic auxiliary mechanism. The chamber is combusted (the process of pelletizing and briquetting biomass materials is omitted), and the heat generated by it is used to drive the operation of the entire system.

[0038] The third embodiment can be used by enterprises that produce biomass pellets or briquettes to use existing biomass materials for combustion and power generation, and for pelleting or briquetting of biomass fuels, thereby reducing electricity consumption and saving energy and expenses. The waste heat generated in the system is used as a drying system to dry the biomass raw materials. The third embodiment can also be used for agricultural irrigation and other projects to reduc...

Abstract

The invention provides a biomass-burning power generation device and aims to solve the problem that biomass power generation is high in cost, serious in pollution and too narrow in available biomass material range. The technical scheme includes that the biomass-burning power generation device comprises a biomass burner (8), a temperature difference engine (17), a cooler (24), a circulating pump (25), a power generator (26) and a power control system (27), biomass fuel is burnt in the biomass burner (8) and releases high-temperature flame and gas to the temperature difference engine (17), low-temperature circulating liquid brings heat away from the temperature difference engine (17) to enable the temperature difference engine (17) to generate temperature difference so as to generate power output to drive the power generator (26) for power generation, and generated power is adjusted by the power control system and then output to the outside. The biomass-burning power generation device can be used for small-scale power generation of enterprises, institutions and the like, can be used for power generation of vehicular moving platforms, shipborne moving platforms, aircraft moving platforms and the like and can be used for distributed-type grid-connected power generation.

Description

Technical field [0001] The invention relates to a biomass power generation device, particularly a biomass combustion power generation device. Background technique [0002] The existing biomass combustion power generation devices are generally divided into the following three types: [0003] 1. Using a large biomass boiler, the steam produced is used to drive a steam turbine and a generator to generate electricity. [0004] 2. Use a large-scale biomass gasification system to gasify biomass by high-temperature cracking, and then go through processes such as decoking, cooling, and filtration to obtain biomass gas. The biomass gas is burned in the gas turbine to generate power. Drive the generator to generate electricity. [0005] The above two kinds of biomass power generation are large-scale power generation projects. The generated energy is generally provided to the power grid. The main disadvantages are that the investment is very huge, requires a lot of infrastructure, and consumes ...
