Embodiment Construction

[0053] The content of the present invention will be further described below in conjunction with the accompanying drawings, so as to help understand the content of the present invention.

[0054] Such as figure 1 As shown, it is a schematic structural view of the solid fuel furnace of the present invention. A furnace 2 is arranged in the furnace body 1, and a pushing device 4 is arranged on the furnace body 1 at the front end of the grate, and the grate installed obliquely in the furnace is a step-by-step The combined grate includes two parts: the fixed wet grate 3 arranged obliquely and the reciprocating slag pushing grate 8 connected to the lower end of the fixed wet grate 3. The reciprocating slag pushing grate 8 includes a fixed grate and The slag pushing part is driven by the driving mechanism to reciprocate along the upper surface of the fixed grate 3, such as Figure 5 and Figure 6 shown. An air distribution chamber is located under the grate in the furnace body 1. A...

Abstract

The invention discloses a solid fuel furnace and a stepped combined fire grate for the same. A hearth is arranged in a furnace body; an inclined fire grate is arranged in the hearth; a material pushing device is arranged on the furnace body at the front end of the fire grate; the fire grate is the stepped combined fire grate which comprises a fixed wet type fire grate part which is obliquely arranged and a reciprocating slag pushing fire grate part connected to the lower end of the fixed wet type fire grate part; and the reciprocating slag pushing fire grate part comprises a fixed fire grate and a slag pushing part which is arranged above the fixed fire grate and can be driven by a driving mechanism to do the reciprocating motion along the upper surface of the fixed fire grate. The fire grate of the solid fuel furnace is not easy to damage; the service period of the furnace is long; the temperature of the hearth is higher; and the thermal efficiency of the fuel can be increased and the emission of harmful gases is reduced.

Description

technical field [0001] The invention relates to a solid fuel furnace, in particular to a solid fuel furnace using a walking combined fire grate. The fire grate is composed of a fixed wet type fire grate and a reciprocating type fire grate. Background technique [0002] Solid fuel furnaces use solid substances such as coal, wood, charcoal, coke, and solid biomass as fuel, mainly including the hearth and grate in the furnace body, and large fuel furnaces also include blowers. Usually the solid fuel is leaked onto the grate through the fuel bin, and the air is supplied from the bottom of the grate to the top of the grate, and the fuel on the grate is burned in the furnace. The grate is generally divided into fixed type and running type, and the moving type has chain type grate and reciprocating grate. The moving grate carries the fuel from combustion to combustion termination to slag formation and slag discharge. Since the grate is moving and made of metal materials, the grate...
