Burner and ignition combustion control method thereof

Abstract

The invention discloses a burner. The burner comprises a burner body, multiple sets of fire rows arranged on the burner body and a fuel gas channel for providing fuel gas for the burner body. The burner is characterized in that the fire rows are divided into separate ignition fire rows, special ignition channels are formed in correspondence to the ignition fire rows, and stop valves are arranged on the portions, of the fuel gas channel, outsides the ignition channels. Before ignition, other fire rows except the ignition fire rows do not need provided fuel gas, when ignition starting of a fuelgas heating hot water furnace, a fuel gas boiler and other fuel gas hot water equipment succeeds, fuel gas is supplied to other fire rows, and other fire rows are irrigated through fire transfer. Therefore, escape of fuel gas during ignition is avoided, the comprehensive energy operation efficiency of the fuel gas heating hot water furnace, the fuel gas boiler and other fuel gas hot water equipment is improved, the effect of saving energy and reducing emission is achieved, deflagration during ignition is avoided, and the safe stability of fuel gas products during long-term use is improved. Theinvention further provides an ignition combustion control method of the burner.

Description

technical field [0001] The invention relates to the technical field of components of a fluid heater, in particular to a burner and an ignition combustion control method thereof. Background technique [0002] For gas heating water heaters or gas modular boilers that use atmospheric burners but do not use segmented burners, when the gas heating water heater starts to ignite, the gas proportional valve of the gas heating water heater starts to open, and the gas heating heat All the burners (fire row) of the water heater start to feed gas, the ignition needle discharges at high voltage, ignites the gas, and transfers the combustion heat of the gas through the heat exchanger. [0003] When the existing gas heating water heater is started to ignite, all burners or part of the burners of the gas heating water heater (for gas heating water heaters using segmented burners) will be fed with gas. Before ignition and when the burner fails to ignite successfully due to repeated ignition...

AI Technical Summary

Problems solved by technology

During the continuous ignition and flameout operation of the gas-fired modular boiler, before the gas is ignited and when the burner cannot be successfully ignited due to repeated ignition due to some fault reasons, the gas is not burned and is directly discharged into the atmosphere. , resulting in a waste of gas resources and pollution to the atmospheric environment

[0004] When the existing gas-fired heating water heater or gas-fired modular boiler is started to ignite, a large amount of gas is flooded in the combustion chamber, which increases the possibility of gas deflagration and potential safety hazards, and reduces the safety of gas products.
