From the various parts of the burner, let's talk about the industry trends at that time. In the burner industry, according to the required fuel, it can be roughly divided into three categories: pulverized coal burners, oilfired burners, and gas burners. Pulverized coal burners have two types: swirl type and direct current type.
Use pulverised coal or petcoke, anthracite, oil, natural gas or any mixture of these as well as alternative fuels (such as plastic and wood chips, sewage sludge). The results are the same.
First, we moved away from burning coal inside our homes, concentrating the production of soot into a few large power plants and moving the soot plumes outside of cities.

A few integrated gasification combined cycle (IGCC) power plants have been built, which burn coal more efficiently. Instead of pulverizing the coal and burning it directly as fuel in the steamgenerating boiler, the coal is gasified to create syngas, which is burned in a gas turbine to produce electricity (just like natural gas is burned in a ...
The Coal Generator is a power generator building that generates power by burning Coal, Compacted Coal or Petroleum Coke and Water. It is the first fully automated power source the pioneer has access to and also the first power source to use a mined resource. One Coal Generator produces 75 MW at 100% clock speed. At 100% clock speed, one Coal Generator consumes 45 m3 Water/min, no matter what ...

Pulverized coal is used in modern thermal power plants. It is a powdered form of coal, coal that is grounded into a dustlike size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning process.

Pulverization of coal is currently the favored method of preparing coal for burning. Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.
