Problems solved by technology
[0006] The burning of biomass particles on a fire bed requires high density of biomass particles to be resistant to burning and to deposit a charcoal layer of sufficient thickness. Once the biomass solid fuel is too loose, burns too fast, and the charcoal layer is unstable, the entire burning biomass will also be destroyed. bad control
[0007] It can be seen from the above that biomass is burned on a fire bed to realize the thermal process, and it is impossible to achieve a stable and relatively small scale of combustion.

Embodiment Construction
[0029] Regarding the work of the biomass pump, the energy consumed by the pressure applied to the biomass by the piston or plunger, because the thermal detour combustion does not have strict requirements on the biomass solid briquette injected into the high pressure combustion chamber, when the positive pressure is greater than the design of the high pressure combustion chamber When under pressure, the biomass pump can inject the biomass into the high pressure combustion chamber.
[0030] The aforementioned positive pressure comes from the technical term for the method of adding powder or coal slurry fuel to the high-pressure combustion chamber of coal-fired power generation, and has the same meaning. The basic compression is obtained, and the added pressure after deducting irreversible losses is greater than the design pressure of the high-pressure combustion chamber, and the biomass can be injected into the high-pressure combustion chamber.
[0031] Regarding the heat exchan...

The invention belongs to the technical field of energy and power engineering, and relates to a method for generating high-temperature and high-pressure fuel gas by combusting biomass in a hot roundabout combustion chamber, which establishes a hot roundabout combustion system capable of realizing stable combustion aiming at the defect that a fire bed combustion technology is difficult to accurately control to stable combustion in the development process of a biomass thermodynamic system. Biomass is injected into a high-pressure combustion chamber through a biomass pump to be combusted, generated high-temperature and high-pressure fuel gas detours to the position below fuel and enters a heat exchanger with a fire grate function, and the space of the combustion chamber is heated through the detours fuel gas. Biomass newly injected into the combustion chamber is combusted above the heat exchanger. The fuel gas flows out of the combustion chamber after being heated in the roundabout process, and available high-temperature and high-pressure fuel gas is formed. The mature solid fuel combustion technology is found in the new energy development technology exploration process, and the era of the combined biomass engine is comprehensively created.
Description
[0001] Technical Field: The method of burning biomass in a hot circuitous combustion chamber to generate high temperature and high pressure gas belongs to the technical field of energy and power engineering. Background technique: [0002] In the field of people looking for new energy sources to replace petrochemical energy, it seems that there is no way to convert biomass into high temperature and high pressure gas through direct combustion, and then convert the power to drive locomotives. Especially in terms of agricultural and forestry machinery, the existing new energy technologies cannot provide the same strong power as diesel engines. It is of practical significance for the cheap biomass energy produced by agriculture and forestry to become conventional power energy through the development of new technologies and new machinery, and it is the only choice for historical development to drive agricultural and forestry machinery. [0003] Realizing the conversion of biomass in...
