Abstract

The invention provides a fire grate and a manufacturing method thereof. The fire grate is made of a marketable material or is made of a part which has the uniform thickness, the high casting accuracy and the simple shape. The fire grate is used in an incinerator and comprises a first alloy steel material and a second alloy steel material different from the first alloy steel material.

Description

technical field [0001] The invention relates to a fire grate and a method for manufacturing the fire grate. Background technique [0002] Conventionally, a motorized grate type incinerator is known as an incinerator in a waste treatment facility for detoxifying hazardous substances generated during incineration treatment of waste. The mobile grate type incinerator has a fixed furnace array and a movable furnace array arranged side by side along the width direction of the incinerator. The array of fixed furnaces and the array of movable furnaces are arranged alternately in a stepwise manner along the longitudinal direction of the incinerator (the transfer direction of the object to be incinerated). [0003] In recent years, a large number of waste treatment facilities have additionally installed boilers and turbine generators to function as power plants that generate electricity as heat recovery facilities in addition to the incineration treatment function. Power plants nee...
