Application of pulverized coal combustion technology to small and medium electric boilers

Model and structure characteristics of small and medium-sized electric boilers :

Small and medium-sized electric boilers can be divided into two categories: fire tube boilers and water tube boilers. According to the combustion method, they can be divided into manual combustion boilers and automatic combustion boilers. Among them, the automatic combustion boiler has a chain furnace, a vibration furnace, a coal pulverizer furnace, a reciprocating furnace, a boiling furnace, a pulverized coal furnace, etc.; according to the fuel type, it can be divided into three types: coal combustion, fuel oil and gas; Can be divided into fast, semi-fast and bulk.

Application of pulverized coal combustion technology to small and medium electric boilers

1. On small and medium-sized boilers, the use of pulverized coal combustion technology has many advantages. The combustion efficiency is higher than that of the layer furnace, and the furnace temperature is high, which is suitable for a wide variety of coal types. It can be used in the technical transformation of the boiler of “oil to coal”, and it can be operated, and it can receive good results of energy saving and emission reduction.

2. When the small boiler is converted into coal-fired powder, the combustion path is short and the combustion path is short. To reduce the fly ash combustibles, the combustible coal such as bituminous coal should be used.

3. Concentrated milling and dispersing powder supply have the advantages of low initial investment, low milling cost, easy management and ensure fuel quality.

4. When renovating, it is necessary to adopt a number of mature and advanced technologies for comprehensive transformation in order to obtain better energy saving and emission reduction effects.
