Abstract

The invention discloses an automatic control system for a dual fuel combustor. The automatic control system comprises a control device sleeved with an electric executer. The control device is connected with a combustion supporting draught fan, a fuel metering pump set, a gas flow adjusting valve, a flue gas valve, a combustion supporting valve and an atomization valve. The combustion supporting draught fan is in control connection with the combustion supporting valve. The flue gas valve, the combustion supporting valve, the atomization valve, the fuel metering pump set and the gas flow adjusting valve are in pipeline connection with a steam boiler. The steam boiler is in signal connection with the control device. By means of the automatic control system for the dual fuel combustor, accurate control over electric executers of the fuel amount, the gas amount, the combustion supporting draught fan, an atomization draught fan, flue gas circulation and the like can be achieved, the best air / fuel ratio is achieved, and the good effects that the discharge amount of NOX products is reduced, and energy is saved are achieved.

Description

technical field [0001] The invention relates to an automatic control system of a dual-fuel burner. Background technique [0002] With the emphasis on environmental protection in my country and the world, the combustion of traditional burners is not sufficient, the fuel consumption is large, and the NO x Issues such as excessive emissions are increasingly to be resolved. The control accuracy of the traditional burner control system is not high, so that after the burner establishes a flame, it can only roughly adjust the ratio of fuel oil to fuel. Based on the design and production of burners for many years, our factory combined the combustion technology of fuel oil and gas for the first time according to the production contract of dual-fuel burners, and proposed a dual-fuel burner control system to control the fuel oil of the burner. Precise adjustment; the air flow is precisely adjusted through fan frequency conversion technology and damper opening control technology; at t...
