摘要： The present invention relates to an injection noncatalyst denitrogen oxide process control system, in which a reducing agent (such as ammonia), carriers and additional gases are injected into the flue gas of a combustion device. The NO.sub.x in the flue gas will be reduced into nitrogen (N.sub.2) and water (H.sub.2 O). A pressure measurement device and a thermocouple device are installed in an injector for measuring the pressure difference and the temperature of the flue gas respectively, and then be converted into a voltage signal and a thermocouple signal respectively. Both of the signals will be transferred into a controller that is controlled by a computer. The controller can control the flow mass of the reducing agent, carriers and additional gases to the flue gas. Therefore, the reduction reaction of the NO.sub.x can be controlled, thereby maximizing the rate of denitrogen oxide (deNOx) and minimizing the discharge amount of the reducing agent.

摘要： Disclosed is a structure of a burner which can be fueled with gas fuel or oil fuel. The main features includes: a specially designed swirl generator; an annular hollow gas gun; an oil gun received in the gas gun where the gas jets of the gas gun and the oil jets of the oil gun have an predetermined angle with respect to the centerline. Under designed operating conditions, a swirling air flow can be generated with a low pressure drop and low turbulences, which is beneficial to flame stability, reducing flame temperature, and delaying the mixing of air and fuel, thus inhibiting the formation of NO.sub.x. Staging air and flue gas recirculation are available for further reduction of nitrogen oxides.
