The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
When we talk about CFBC in the area of industrial boiler, it usually means the circulating fluidized bed combustion. The circulating fluidized bed (CFB) is a type of fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion.
Based on the different methods involved in ash deposit over the heating surface, two types of ash deposition are observed, i.e. slagging and the fouling. Boiler slagging and fouling are two main factors that adversely affect the efficiency of boilers.
The efficiency of a coal-fired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, i.e. mainly carbon loss and dry gas loss.
The special spray gun for pulverized coal boilers is a kind of equipment that atomizes fuel oil (light oil, heavy oil, residual oil, etc.) to make the fuel oil into UM-level particles. Through air distribution and ignition, the fuel oil can be sufficiently burned. It is widely used in the boiler industry.
