Overview:
QXX series CFB boiler is a new generation low speed inner circulation circulating fluidized bed hot water boiler, this type boiler inherits the traditional technology advantages, at the same time, it makes big breakthrough in whirlpool fluidized combustion technology, vortex wind separation structure design and return feeding technology.

Application:
QXX low speed CFB hot water boilers are mainly used in city, enterprise heating system.

Benefits:
1. Membrane water wall can make the boiler furnace, separator, and return feeding system as a whole, the overall boiler structure is compact.
2. The separator structure and parameter design make great progress, effectively improve boiler combustion efficiency and separation efficiency.
3. The return feeding system is composed by two pieces of membrane water wall, the partial heat brought by fly ash is absorbed by the water tubes, reduce fly ash temperature, no coking will be caused by secondary combustion in the feeding system.
4. The wear design adopts several measures, coal fuel has a good adaptability, and the swirl fluidized combustion technology makes the materials swirl fluidized combustion in the combustion chamber to improve boiler combustion efficiency. Besides, the failure rate is reduced, and it can long-time operation.
5. Using low-temperature combustion technology to effectively reduce harmful gases generated, desulfurization can be done in the furnace, the boiler is environmentally friendly.
