AI Technical Summary

Technical Problem

The existing burner design of gas-fired water heaters results in uneven mixing of gas and air, leading to unstable combustion and affecting performance.

Method used

A contraction channel section and a main channel section are set in the ejector channel of the burner, and a group of turbulence protrusions is set on the inner wall of the main channel section. The turbulence protrusions are staggered along the airflow direction to enhance the mixing effect of gas and air.

Benefits of technology

It improves the uniformity of gas-air mixing, enhances combustion stability and reliability, facilitates the thinning design of the burner, and improves the performance of gas-fired water heaters.

Abstract

The application belongs to the technical field of gas equipment, and particularly discloses a fire grate, a burner and a gas water heater. The fire grate comprises an injection part with an injection channel, the injection channel comprises a contraction channel section and a main channel section, a turbulence bump group is arranged on the inner wall surface of the main channel section, the turbulence bump group comprises two turbulence bumps, the two turbulence bumps are arranged in a staggered manner along the airflow direction, and the projections of the two turbulence bumps along the airflow direction are at least partially staggered. The application can prolong the residence time of the gas and the air in the injection channel, thereby improving the combustion sufficiency and the combustion stability.
