Abstract

Disclosed in the present application are a fire grate, a burner and a gas water heater. The fire grate comprises a single fire-grate body, a support base and a burning panel. In the technical solution of the present application, the original structure of a top burning panel provided with fire holes is changed to a structure of forming the burning panel using a plurality of layers of metal meshes. By means of such an arrangement, the intensity of gas pressure in the fire grate can be reduced, thereby reducing the heat intensity per unit of area of the burning panel. In addition, by means of the burning panel in the form of multiple layers of metal meshes, the fire hole area of a fire outlet of the fire grate is increased, such that after coming out of the burning panel, a gas flow, which is preliminarily mixed, is further mixed with air at the burning panel to form a sufficiently mixed gas; and finally, a stable and uniform flame is formed above the burning panel. The heat load of the fire grate provided in the present application is significantly increased, the range of adaptability of the fire grate is also correspondingly expanded, and thus, the performance of flue gas emitted during instantaneous combustion is better, and the amount of NOx generated after burning is also lower.
