Summary of structural characteristics of oil (gas) boilers

日期: 2017年08月29日 Author: Stand Original Date: August 29, 2017

Compared with oil-fired (gas) boilers and coal-fired boilers, due to the different fuels, they have the following characteristics in structure:

(1) Fuel is injected into the furnace of the boiler through the burner, and the fire chamber is used for combustion without the need for grate facilities;

(2) Because no ash and slag are generated after oil and gas combustion, there is no slag discharge outlet and slag removal equipment for oil (gas) boilers;

(3) The physical, chemical oil, gas or gas sprayed into the furnace will easily form explosive gas if it is extinguished or mixed with air within a certain range. Therefore, oil (gas) boilers must use automatic combustion systems, including flame monitoring, flameout protection, explosion protection And other safety facilities;

(4) Because the heat generated by oil and gas is much larger than the heat generated by coal, its furnace heat intensity is much higher than that of coal-fired furnaces. Compared with coal-fired boilers of the same capacity, the boiler has a small volume, a compact structure, and covers an area small;

(5) The combustion process of the oil (gas) boiler is carried out in the furnace, so the front and rear arches are set in the furnace, and the furnace structure is very simple.
