Products introduction:

ZG boiler biomass circulating fluidized bed boiler can use direct burning fuel such as straw husk, shaped biomass, pure coal or coal and biomass co-firing fuel, which overcomes the problems of easy burning of slag and ash in biomass fuel. The boiler can be used for power generation, central heating, and urban residents' winter heating. The biomass fluidized bed boiler is a thermal energy equipment using a circulating fluidized bed combustion technology for the biomass boiler. In the fluidized bed, the bed material has a high heat capacity, and provides sufficient preheating and drying heat source for the biological waste. By adding limestone to the furnace, the emission of sulfur dioxide in the flue gas can be significantly reduced. The combustion technology using low-temperature and air-graded air supply can significantly suppress the formation of NOx, and is a clean combustion equipment.

Biomass circulating fluidized bed boiler performance advantages:

1. Material-saving: high-efficiency separation and cyclic combustion in the fuel pellet furnace, the combustion efficiency is up to 99%, and the running fuel loss is reduced by more than 3%;

2. Power saving: the boiler runs at low bed pressure, the power consumption of the fan is reduced, and the power consumption rate of the plant is low, which can save more than 30% of the power consumption of the fan;

3. Low wear: the boiler heating surface has almost no wear, the maintenance frequency is low, and the annual running time can reach 8000 hours or more;

4. High separation: The optimized center-cylinder offset high-efficiency cyclone separator ensures high-efficiency separation with separation efficiency of over 99.6%.
