Liquid-oxygen oxygen combustion-supporting device of biomass particle steam boiler

Abstract

The invention relates to a liquid-oxygen oxygen combustion-supporting device of a biomass particle steam boiler. The liquid-oxygen oxygen combustion-supporting device is characterized in that a liquid-oxygen oxygen combustion-supporting device is matched in an inner cavity of one of an induced air duct of a coal economizer or an induced air duct of the boiler, an outlet end and an inlet end of theliquid-oxygen oxygen combustion-supporting device separately stretches outside the inner cavity of the induced air duct, the inlet end of the liquid-oxygen oxygen combustion-supporting device is connected to one end of an air inlet conveying pipe through a connecting joint, and the other end of the air inlet conveying pipe is connected to a joint end of a liquid outlet valve on a Dewar flask; theoutlet end of the liquid-oxygen oxygen combustion-supporting device is connected to one end of an air outlet conveying pipe through a connecting joint and the other end of the air outlet conveying pipe communicates to an air duct of an air blower. The device has the advantages of being safe, efficient, energy-saving, simple in structure and low in cost. As the liquid-oxygen oxygen combustion-supporting device is configured at a tail flue outlet of the boiler and a heating device is replaced by waste heat of the boiler, the liquid-oxygen oxygen combustion-supporting device is energy-saving andcost-saving. The device can be assembled on new and old boilers to use, so that the device is widely popularized and applied conveniently.

Description

technical field [0001] The invention relates to the technical field of combustion-supporting devices, in particular to a liquid oxygen and oxygen combustion-supporting device for a biomass particle steam boiler. Background technique [0002] When the boiler is burning, it is generally necessary to install a combustion-supporting device to improve the combustion efficiency. However, in the existing technology, the external air is directly introduced into the boiler for combustion-supporting, but this method cannot be used in a very fast Improve the combustion effect to a large extent, because the air contains moisture and other gases, which makes the combustion insufficient and black smoke, which seriously affects the air pollution environment, wastes a lot of biomass raw materials, and greatly reduces the combustion support; for This defective patent number 2018215974467 invented a combustion-supporting device for a biomass pellet boiler, which is equipped with oxygen produc...

[0002] When the boiler is burning, it is generally necessary to install a combustion-supporting device to improve the combustion efficiency. However, in the existing technology, the external air is directly introduced into the boiler for combustion-supporting, but this method cannot be used in a very fast Improve the combustion effect to a large extent, because the air contains moisture and other gases, which makes the combustion insufficient and black smoke, which seriously affects the air pollution environment, wastes a lot of biomass raw materials, and greatly reduces the combustion support; for This defective patent number 2018215974467 invented a combustion-supporting device for a biomass pellet boiler, which is equipped with oxygen production, vacuum, dehumidification, voltage stabilization, and preheating mechanisms in front of the boiler. This device increases the concentration of oxygen and dehumidifies, so that The combustion-supporting effect is remarkable; however, this set of combustion-supporting devices has a complex structure, a large floor space, and high investment costs. Each set needs to invest more than 300,000 yuan, so it is not easy to popularize and apply
