Biomass reactor control system

The present invention relates to the field of biomass energy equipment technology, and in particular to a biomass reactor control system.

Biomass is the most widespread substance on earth. It includes all animals, plants and microorganisms, as well as many organic matter derived, excreted and metabolized by these living substances. Moreover, biomass is an important renewable energy source. It is widely distributed, and its quantity is huge, and raw materials can be supplied continuously. Traditionally, the use of biomass fuels is still mostly using direct combustion, and the utilization rate is low. Biomass burners that are commonly used on the market are classified into two types: direct-fired and gas-fired.

Direct-burning is like the way of burning stoves in rural areas. It is more special to install some simple equipment on the feeding and firepower, but the burning value is constant. With this direct burning method, it is limited. The combustion value, under the general acceptable volume limit, usually does not reach higher heat and heat, unless the volume is increased, which will greatly increase the cost. And according to this combustion method, the cost is 1.47 times that of coal in the case of the same heat energy. Although it is an environmentally friendly product, it cannot replace the market position of coal.
