Triode current stabilizing self-control preheating burner

Abstract

The invention discloses a triode current stabilizing self-control preheating burner. The burner comprises a burner body. A mixing cavity and a burning cavity are formed in the burner body. A fuel gas pipeline communicated with the mixing cavity is arranged at the tail end of the burner body. The fuel gas pipeline is provided with a fuel gas valve. An annular air duct is further arranged on the inner wall of the burner body and communicated with the mixing cavity. A partition plate for separating the air duct from the fuel gas pipeline is arranged between the air duct and the fuel gas pipeline. A partition ring is further arranged between the mixing cavity and the burning cavity. An air inflow structure is arranged on an inlet of the air duct. A control motor connected with the air inflow structure is further arranged on the outer side of the burner body. A temperature control circuit and a triode current stabilizing circuit which are connected in series are further arranged in the control motor. The triode current stabilizing self-control preheating burner can better promote sufficient burning of fuel gas, meanwhile, heat generated during burning of the fuel gas can be further utilized, and heat losses are reduced.

Description

technical field [0001] The invention relates to a burner, in particular to a triode steady-flow self-control type preheating burner used in a carbon roasting furnace. Background technique [0002] At present, the burners used in domestic carbon anode roasters are mostly old-fashioned air distribution direct injection burners. The air distribution of this kind of burner is manually controlled. Due to the influence of the operator's skills, it will make the air distribution of this burner difficult to control. The air intake volume does not match the gas input volume, which will often cause insufficient combustion in the fire channel. or partial overheating. When the combustion is not sufficient, the gas with a lower temperature is equivalent to blowing cold air into the furnace, and at the same time, the uncontrolled mechanical air door continuously sucks in cold air into the furnace under the action of negative pressure in the furnace. Under these dual effects, the thermal...
