What are the uses of circulating fluidized bed boiler?

With the continuous innovation of industrial technology, the boiler industry has produced a kind of circulating fluidized bed boiler equipment with high efficiency and low pollution through innovative research and development. What are the uses of circulating fluidized bed boiler? Here, ZOZEN Boiler will introduce the specific operation principle and the application of circulating fluidized bed boiler.

Working principle and characteristics of circulating fluidized bed boiler

Circulating fluidized bed boiler adopts fluidized combustion mode. After the fuel is crushed to a proper particle size by a crusher, it is fed from the upper part of the air distribution plate of the combustion chamber by a coal feeder, mixed with the hot boiling materials in the combustion chamber, heated rapidly, and the fuel quickly catches fire and burns. Under the action of high air velocity, a large number of solid particles are carried out of the combustion chamber. After being separated by a gas-solid separator, the separated materials are returned to the combustion chamber by a material return device to continue to participate in combustion.

The features of circulating fluidized bed boiler are as follows:

1) wide fuel adaptability

2) stable and efficient combustion

3) Excellent environmental protection performance

4) the fuel preparation system is simple

5) Good load regulation performance.

6) Local areas of furnace heating surface are easy to wear.

7) The energy consumption level of the unit is high.

8) The level of automation control is high.

9) The high circulating rate fluidized bed boiler has a large furnace and a large initial investment.

Use of circulating fluidized bed boiler

As a type of boiler with clean combustion technology, the use of circulating fluidized bed boiler is mainly divided into the following aspects:

1. Enterprise-owned boiler

Steam consumption is large in the production of paper, chemical industry, food and building materials, and some enterprises choose circulating fluidized bed boiler for heating.

2. Heating companies provide central heating.

Thermal power companies purchase circulating fluidized bed boilers to provide steam for enterprises, or to heat units and residential buildings, etc.

3. Power plant

At present, ZOZEN Boiler is one of the good circulating fluidized bed boiler manufacturers in the market, and its products cover five categories: gas boiler, biomass boiler, heat-conducting oil boiler, coal-fired boiler and circulating fluidized bed boiler. Low nitrogen circulating fluidized bed boiler is the key product of the company, which is divided into DHX series circulating fluidized bed steam boiler, SHX series circulating fluidized bed steam boiler, SHX series circulating fluidized bed hot water boiler and QXX series low nitrogen circulating fluidized bed hot water boiler.

ZOZEN low nitrogen circulating fluidized bed boiler is widely used, and its energy-saving and emission-reducing performance is well applied in many well-known enterprises. The customer feedback has a very good environmental protection effect, and it saves a lot of expenses for enterprises every year, thus realizing the unification of social and economic benefits.
