Abstract
The invention discloses an energy-saving hearth for normal-pressure chain boiler. The energy-saving hearth comprises a front arch, a rear arch and chain furnace grates, wherein the chain furnace grates are arranged below the front arch and the lower arch; the front arch is of a furnace wall structure; the rear arch is of a steel-made-type water sleeve structure; the front arch is a furnace wall which is built and poured by fireproof materials; the rear arch is provided with a dip angle so as to exert the effects of flue gas guidance and hot carbon particle conveying; the upper part of the front end of the rear arch is provided with a vertical-type water discharge pipe communicated with a water tank in the furnace; furnace walls at two sides and the furnace wall at the rear side of the rear arch are communicated with a water layer of a boiler body so as to keep water circulation and thermal exchange in the arch. According to the technical scheme provided by the invention, the energy-saving hearth has the characteristics of simple structure, low material consumption quantity, high thermal efficiency, full combustion and running safety and reliability, and is especially suitable for chain boilers combusting bituminous coal; the technical principle is also suitable for layer-combustion boilers combusting other boiler coal.
Description
Technical field:
The invention belongs to normal pressure chain-grate boiler technical field, relate to a kind of furnace wall of total ignite heat exchange and flue gas guide function and the chamber structure that steel formula water jacket chimney arch forms.
Background technology:
The normal pressure chained coal fired boiler be widely used in recent years China town and country office, school, army and each enterprises and institutions, city dweller community heating, have a bath, the field such as drinking-water.Because the starting of normal-pressure boiler manufacturing enterprise is late, small scale, lack qualified technical personnel, and there is no independently technical system, and this industrial chain boiler art designs manufacture consumable quantity of most classes is large, the boiler operatiopn thermal efficiency is generally lower.
Summary of the invention:
The object of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of combustion conditions good, the chamber structure that heat transfer efficiency is high, saved raw material, improved the thermal efficiency.
The objective of the invention is to solve by the following technical programs:
A kind of Energy saving chamber of furnace normal pressure chain-grate boiler, comprise face arch, rear arch and traveling-grate stoker, below face arch and rear arch, is provided with traveling-grate stoker; Described face arch is furnace wall structure, and rear arch is steel formula jacket structure for water.
Described face arch is to build by refractory material the furnace wall of building and casting.
Described rear arch is provided with inclination angle, guides and carry red-hot carbon granule effect, rear arch upper front end to be provided with the vertical water comb with the performance flue gas to be communicated with the stove inner water tank, and rear arch both sides furnace wall and rear side furnace wall are communicated with the boiler body water layer, keep water circulation and heat exchange in arch.
Described vertical water comb is set to transverse drain and longitudinal drainage pipe front and rear row interlaced arrangement.
The locus of described vertical water comb vertically arranges or is obliquely installed.
Technical scheme of the present invention has simple in structure, and consumable quantity is little, and the thermal efficiency is high, sufficient combustion, and characteristics safe and reliable to operation, adapt to the chain-grate boiler application of bituminous coal especially.Other arrange the grate firing boiler of stove coal its know-why simultaneous adaptation.
The accompanying drawing explanation:
Fig. 1 is the structural representation of energy-saving hearth chimney arch in the present invention;
Fig. 2 is the side view of rear arch upper front end vertical water comb;
Wherein: 1 is face arch; 2 is rear arch; 3 is traveling-grate stoker; 4 is the vertical water comb; 5 is rear arch both sides furnace walls.
The specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Referring to Fig. 1,2, energy-saving hearth comprises face arch, rear arch, traveling-grate stoker, vertical water comb and rear arch both sides furnace wall.
Described Energy saving chamber of furnace structure is comprised of face arch, rear arch and traveling-grate stoker.Face arch is existing furnace wall structure, brings into play radiation again, the mirror reflex, and the ignition zone that radiant heat is delivered to fresh fuel promotes burning, rear arch is steel formula jacket structure for water, is convenient to conduct heat to reduce consumable quantity, improves the thermal efficiency.
Described rear arch keeps that inclination angle should be arranged, and with the performance flue gas, guides and carry red-hot carbon granule effect.The arch upper front end is provided with the vertical water comb and is communicated with the stove inner water tank, and both sides and rear side are communicated with the boiler body water layer, keeps water circulation and heat exchange in arch.
Described vertical water comb is set to transverse drain, vertically the front and rear row interlaced arrangement.The locus of vertical water comb can vertically arrange, also tiltable setting.
The notable feature of burner hearth combining structure is that face arch is still built and built and casting with existing general refractory material, and rear arch is steel formula water jacket chimney arch, and the arch upper front end is provided with the vertical water comb, and block is still built for refractory material in both sides.
After boiler is lighted, through the face arch radiation, the rear arch guiding, high-temperature flue gas is through aditus laryngis, and the vertical water comb enters heat-exchange system heat exchange in stove.Rear arch and vertical water comb carry out heat exchange in advance simultaneously, make the large raising of the thermal efficiency.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet not in order to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, still belong in the scope of technical solution of the present invention.
