Guide: 1. Direct combustion technology Biomass direct combustion technology is to burn biomass as fuel, and use heat energy to satisfy production and life. The technical requirements for direct combustion are very low, and the combustion method is relatively simple. The particulate matter, sulfur oxides, and nitrogen oxides produced during combustion will seriously pollute the environment.

2. Biomass boiler combustion
With the continuous improvement of boiler technology, it has now become an advanced biomass combustion technology. Biomass is used as the fuel for boiler combustion. By controlling the combustion of fuel in the boiler, the utilization efficiency of biomass is improved.
Biomass boilers are divided into two types: water-cooled vibrating furnaces that burn pure biomass and circulating fluidized bed boilers that mix biomass. The water-cooled vibrating furnace has poor combustion adaptability, low combustion efficiency, high moisture content, and high cost. Compared with the circulating fluidized bed mixed-burning biomass boiler, the cost is very low, its combustion adaptability is very strong, the operation is safe, and the load range is wide. Therefore, the circulating fluidized bed mixed-burning biomass boiler is more suitable for my country's national conditions.
In addition, chain grate furnaces and reciprocating grate furnaces are also suitable for biomass combustion. The grate slices of chain grate furnaces can be cyclically cooled. Reciprocating grate furnaces have great advantages in combustion size and fuel leakage. The combustion of biomass fuels on these types of boilers is still in the exploratory stage, and the technology needs to continue to mature.
