Embodiment Construction

[0030] The biomass thermal unsteasing furnace is in the initial period of ignition. By combustion of combustion on the chain row, the biomass raw material such as a quantitative straw is delivered from the feed port to the reaction kettle, adjust the steering of the reaction kettle to the furnace and reactor. Heating, when the biomass thermal extract furnace reaches the pyrolytic gasification temperature of the biomass raw material, stop the addition of flammable products, preheating the biomass thermal default furnace, and is consumed by the thermal flulation reaction after preheating. The straw in the reactor is followed by repeated artificially charged, unloading, in order to perform thermal amplifiation to generate gas. During the operation of the biomass thermal extract, since the biomass such as straw has a certain amount of water, the temperature in the rotating reaction is reduced, resulting in the pyrolysis temperature, and the subsequent addition of flammable will cause ...

Abstract

The invention provides a control method of a biomass pyrolysis gasifier. The control method comprises the following steps: acquiring a fuel gas temperature value; and according to the fuel gas temperature value, judging whether at least one of the amount of substances in a rotary reaction kettle, the rotating speed of a combustion fan and the rotating speed of a flue gas fan is adjusted or not. According to the control method of the biomass pyrolysis gasification furnace, whether the temperature of the biomass pyrolysis gasification furnace in the operation process is constant within a certain range or not is judged by obtaining the fuel gas temperature value, and the temperature of the biomass pyrolysis gasification furnace is controlled by adjusting the amount of substances in the rotary reaction kettle, the rotating speed of the combustion fan and the rotating speed of the flue gas fan, and thus the temperature of the biomass pyrolysis gasification furnace is kept within a certain range, so that the biomass pyrolysis gasification efficiency is improved, and fuel gas can be stably and continuously generated.

Description

Technical field [0001] The present invention relates to the field of biomass heat dissipation, and in particular, to a control method of a biomass thermal decapulizing furnace. Background technique [0002] In recent years, with the development of my country's science and technology, the requirements of environmental protection are extremely eyebreaking, the amount of clean gas demand is increased, from the perspective of technology development and application promotion, pyrolysis gasification, biological gasification gas is positive Gradually received extensive attention and attention. [0003] Biomass thermal solutioning technology is a newer straw utilization technology developed in recent years, which is to convert the biomass raw material such as straw into a heat transfer process of gas fuel. Biomass raw materials such as straw under the conditions of hypoxia, partially combustion in the gasification reactor, to provide the heat required for gasification heat absorption, so...
