RESEARCH, DESIGN, AND MANUFACTURE OF ZERO-EMISSION BIOMASS FUEL FURNACE APPLYING FOR ORGANIC COMPOSTING SYSTEMS
Abstract
This paper presents the results of the research, calculation, design and intention of releasing to market a model of a high-efficiency biomass solid fuels furnace, reducing dust, emissions and environmental pollution. It is used in connection with the animal waste (pig manure) treatment chamber system. The distinction and advantage of this furnace is the high efficiency of heat collection due to the use of wasted heat from the furnace core combined with the mixing chamber to take cold air from the environment to cool the furnace core and recover the wasted heat to increase the thermal efficiency of the furnace. From the calculation results, we have parameters such as: furnace dimensions (length x width x height)/(2,160 x 1,430 x 1,668) mm; the grate furnace area is 0.8 m2, the heat capacity of the furnace when burning biomass (corn cob, firewood, rice husk briquette/rice husk pellets,...) is about 300-500 kWth; thermal efficiency about 88.65 %. Especially, this furnace does not emit emissions, which is a new feature of this furnace model.
