Technology and Application of Air Flow Adjustment and Control in Boiler Combustion Area Based on Furnace Atmosphere Field
The importance of boiler air flow control was discussed,and the current status of conventional boiler air flow control technology was elaborated.A local air flow adjustment and control technology based on furnace atmosphere field in the combustion area was proposed,with a focus on introducing furnace atmosphere field measurement technologies such as CO and H2S measurement,as well as the principle of air flow control in this technology.The application situation on a 600 MW thermal power unit was introduced,and an economic analysis was conducted.The results show that this technology can effectively reduce the chemical and mechanical incomplete combustion losses of boilers,avoid non-stop losses and tube burst maintenance losses,and has good economic efficiency.
