ZG CFB Boiler Low NOX Emission Patented Technology
As a new type coal fired energy saving and environmental protection power generation equipment, CFB power plant boiler has been the most practical product and widely used in industries. ZG Boiler has made breakthrough in technology in order to improve the cleaning effect of CFB boiler.
The CFB boiler technology in ZG Boiler
At present, the technology on CFB boiler in our company has improved a lot. The production of ZG Boiler is popular in many large enterprises, and has played a key role in protecting environment. The main advantage of it is reducing the NOX emission.
Optimization of first and second air layout
Optimization of first and second air layout strengths the combustion effect of coal in burning area and lowers the NOX emission in reduction zone.
Gas recycling technology
The usage of gas recycling technology could reduce the oxygen content in first air to 17%～19%, which further promotes the circulating amount of fly ash inside and outside of the furnace. So as to decrease the bed temperature benefit and NOX emission efficiency and desulfurization.
Measurement control system
The following effect could be realized through precise measurements of flow: the primary and secondary air flow can be accurately measured; the grading combustion could be accurately controlled ; combining with the CEMS flue gas, can achieve closed-loop adjustment; can keep the unit in low NOX emission state, and so on.
With this low NOX emission patented technology, the problem such as high SO2 emission, instability combustion, low load in CFB Boiler has been solved perfectly. And the NOX emission in slag in thermal power station has been decreased by 80%一90%, which can effectively reduces the atmosphere environment pollution of boiler, has a great significance in protecting the ecological environment.
