Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The present invention is applicable to the schematic diagram of the fire grate of large particle solid fuel as figure 1 Shown, be made up of stepped fixed fire bar 14 and stepped movable fire bar 13. The schematic diagram of the stepped fixed furnace bar is as Figure 2-Figure 3 As shown, it includes the grate base, which is composed of the first fuel drop-off zone 1 on the upper part, the first main fuel combustion zone 2 on the middle part and the first slagging zone 3 on the lower part, and the first fuel drop-off zone The upper end surface 15 of 1 is an inclined surface, and a rocking support surface 4 is provided under the first fuel sliding area 1 . The first fuel main combustion zone 2 is stepped; the upper end surface of the first slagging zone 3 is plane. The schematic diagram of the stepped movable furnace bar is a...

Abstract

The invention discloses a fire grate suitable for large-grain solid fuels, and provides a fire grate capable of automatically breaking coke and having the function of automatic cleaning. It is composed of a stepped fixed furnace bar and a stepped movable furnace bar. The furnace bar base of the stepped fixed furnace bar is composed of the upper first fuel sliding area, the middle first fuel main combustion area and the lower first slag discharge area; The first fuel main combustion area is stepped; the grate body of the stepped active grate is composed of the upper second fuel sliding area, the middle second fuel main burning area and the lower second slagging area, the second fuel sliding There is a rocking support groove matched with the rocker below the zone; the second fuel main combustion zone is stepped. The stepped solid grate and the stepped movable grate are arranged side by side; the first fuel main combustion zone in the stepped fixed grate and the second fuel main combustion zone in the stepped movable grate have the same stepped structure and form a stove Fuel main combustion zone. Automatic feeding is realized, avoiding coking in a large area.

Description

technical field [0001] The invention relates to the technical field of solid fuel burners, and more specifically relates to a fire grate suitable for solid fuel burners. Background technique [0002] Solid fuel boilers, heating furnaces and other burning appliances generally burn solid fuels such as coal and biomass on a grate composed of multiple furnace bars. At present, each fire bar that forms the fire grate is generally straight and strip-shaped, and a plurality of fire bars are arranged to form a plane, and the fire grate is fixed as a whole. Since the grate as a whole is a plane and cannot move as a whole, when the fuel burns and cokes, it will adhere to the grate, causing insufficient coal combustion and reducing the thermal efficiency of the coal. Therefore, in order to make the coal burn fully, people will regularly clean the grate, and even clean the grate after each combustion. During the process of cleaning the grate, the normal operation of heating and water ...
