Description

technical field [0001] The invention relates to a steam production control system and method of a biomass gasification furnace combined with a boiler. Background technique [0002] In recent years, with the reduction of fossil energy reserves and drastic changes in environmental pollution, it is imminent to find new renewable energy that can replace fossil energy and other disposable energy. Biomass is the most abundant renewable resource on earth, and its effective utilization is of great significance for improving the environment, partially replacing fossil energy and ecologically sustainable development. Biomass gasification is a biomass energy utilization technology with great development potential. Updraft gasifiers, downdraft gasifiers and circulating fluidized bed gasifiers using biomass energy are used in power generation, heating and Applications such as drying have been developed rapidly. [0003] Biomass gasifier combined boiler refers to a combined device that ...
