Multiple group layer combustion-supporting gas making screen device for coal-turned-gas boiler

Abstract

The present invention belongs to the field of boiler technology, is a kind of combustion-supporting gas making device for coal / gas converting boiler. The technological scheme is that the combustion-supporting gas making device includes air pipeline system and oil pipeline and oil cooling system. Each of the air pipes has several double-layer nozzles with inner air pipe and outer oil pipe, air is supplied through the inner pipe connected to air supplier, and oil passage is between the air pipe and the oil pipe. The snake-shaped oil pipes between the oil inlet and the oil outlet is set inside oil cooling tank for cooling. Several double-layer nozzles form one layer of the combustion-supporting gas making screen, and several similar layers are laminated to constitute the combustion-supporting gas making device.

Description

technical field [0001] The invention belongs to the technical field of boilers and relates to a multi-layer combustion-supporting gas-making tube screen device for boilers. technical background [0002] As we all know, the main components of the coal-to-gas boiler are the pot and the furnace. The furnace part generates heat value through combustion, and the pot converts the heat value generated by the furnace combustion into hot water or gas, which is transported through pipelines. To heat the user, therefore, it can be said that the furnace is the supply site of the calorific value. So, how to generate higher calorific value in the furnace hall? In the past, conventional coal-to-gas boilers were usually fed into the coal seam above the grate, and the calorific value of the coal was generated by blowing air from the grate upwards. If the coal seam above the grate was too thick, or the coal quality was not good, the furnace If the exhaust and air supply are not good, the co...

So, how to generate higher calorific value in the furnace hall? In the past, conventional coal-to-gas boilers were usually fed into the coal seam above the grate, and the calorific value of the coal was generated by blowing air from the grate upwards. If the coal seam above the grate was too thick, or the coal quality was not good, the furnace If the exhaust and air supply are not good, the combustion of the coal seam will be poor, and the calorific value produced in this way will be very low, which will seriously affect the calorific value effect of the boiler.
