Combustor fire grate, combustor and water heater

Abstract

The invention relates to the technical field of combustors, in particular to a combustor fire grate, a combustor and a water heater. The combustor fire grate comprises a premixing cavity, wherein thefire outlet end of the premixing cavity is provided with a fire outlet face, the fire outlet face is provided with fire outlet holes, the fire outlet holes comprise a plurality of main fire holes anda plurality of auxiliary fire holes, all the main fire holes are arranged in parallel, and the auxiliary fire holes are formed between every two adjacent main fire holes among part or all of the mainfire holes. According to the combustor, the auxiliary fire holes are formed between every two adjacent main fire holes in the fire outlet face 2-3 of the unique premixing cavity, so that the main fireholes and the auxiliary fire holes are basically formed alternately, good fire transferring and flame stabilizing performance is achieved, combustion noise is lowered, the combustion discharge amountis reduced, better performance experience is brought to consumers, the using comfort of the water heater is improved, moreover, the emission of carbon monoxide can be effectively reduced, and the usesafety of the water heater is improved.

Description

Technical field[0001]The present invention relates to the field of burner, in particular, to burner, burner, and hot water equipment.Background technique[0002]With energy saving and emission reduction, the implementation of coal-to-gas policies, gas water heaters have become long-term development, which has become an indispensable product in consumers. With the improvement of living standards, consumers are getting higher and higher in quality requirements for gas water heaters. Consumers have put forward higher requirements for the comfort and safety of gas water heaters.[0003]The existing gas water heater combustor is mostly an air burner. The fire hole of the air burner has three structures in the inner V hole, the outer V hole, and the plane holes. Although the inner V-hole structure is conducive to the combustion noise but the discharge is relatively Poor, and very easy to have a tempering phenomenon; the outer V pore structure is conducive to emissions, but it is easy to cause...

AI Technical Summary

Problems solved by technology

[0003] Existing burners for gas water heaters are mostly atmospheric burners. The fire holes of atmospheric burners have three structures: inner V hole, outer V hole and plane hole. Although the inner V hole structure is conducive to combustion noise, the emission is relatively low. The outer V hole structure is good for discharge, but it is easy to cause combustion resonance and fire off. The higher flame height of the outer V hole structure will cause adverse consequences such as ablation of the heat exchanger, reducing heat loss. The service life of the exchanger, the performance of the planar structure is between the two

During the operation of the existing burner, there will be safety hazards such as deflagration due to poor fire transmission, and the problem of high carbon monoxide emissions in the flue gas due to unstable combustion flame
