The outer wall of the stove core is square. A square ring-shaped vaporization sleeve is installed at the upper part of the square outer wall of the stove core. The vaporization sleeve is respectively connected with a water inlet pipe and a steam supplying pipe. The steam supplying pipe is connected with a steam jetting pipe below the stove core. A steam jetting hole is below the inner hole of the stove core. The utility model has the advantages of simple structure, good vaporization effect of the vaporization sleeve, good water-coal combined firing effect and strong firing firepower. The coal firing firepower of the high-efficiency water-coal combined firing honeycomb briquet stove is similar to the firepower of liquefied gas firing. In the same firing time, the fuel cost of the firing firepower of the high-efficiency water-coal combined firing honeycomb briquet stove is saved by 20%, compared with the liquefied gas. The utility model has higher firing effect.

Description

Efficient water-coal combined firing honeycomb coal stove

The utility model relates to a kind of the combustion apparatus with patch fuel.

Generally not auxilliary other device that increases combustion that adds of honeycomb briquette stove commonly used, the flame of coal stove is short and burning is fierce inadequately, and the thermal efficiency is lower.Indivedual auxilliary devices that are added with water spray steam are also arranged, but because of the heating surface area of hot water is not enough, the evaporating capacity deficiency of water causes result of use not ideal enough.

The purpose of this utility model provides a kind of water-coal combined firing honeycomb coal stove that square ring-type vaporization cover is housed.

Task of the present utility model realizes with following mode: a kind of efficient water-coal combined firing honeycomb coal stove, in the cooking stove casing, combustion chamber is housed, fire bars and grey thorax are arranged at the combustion chamber bottom, air inlet, airstream deflector and cooktop surface are arranged above the combustion chamber, the combustion chamber endoporus is circular, outer wall is square, square ring-type vaporization is sleeved on the square outer wall of combustion chamber top, the vaporization cover is connected with water inlet pipe and steam delivery tube respectively, the steam delivery tube connection is contained in the steam jet pipe below the combustion chamber, described steam jet pipe is to have jetted hole on the single tube or have jetted hole on ring tube, and jetted hole is arranged in the endoporus lower position that combustion chamber is put honeycomb briquette.Jetted hole has 1 to 30.The jetted hole aperture is in 0.5mm to 2.5mm scope.The ring tube of air jet pipe has a ring to the Fourth Ring.

The utlity model has simple in structure, vaporization cover vaporization effect is good, the water coal for mixing combustion is effective, combusting firepower is violent, its coal-fired firepower surpasses combustion fluid gasification firepower, burning with equal time only fuel cost just save 20% than liquefied gas, with common coal kitchen range than coal with isodose, this kitchen range shorten in time of 1/3rd can boiled common kitchen range 1.6 times water, the vapour of need not vaporizing also improves 20% benefit than common kitchen range.

Below in conjunction with accompanying drawing the utility model is described in further detail: combustion chamber 5 is housed in cooking stove casing 3, fire bars and grey thorax, air inlet 9 are arranged at combustion chamber 5 bottoms, airstream deflector 2 and cooktop surface 1 are housed above the combustion chamber 5, in order to strengthen firepower, fire door airstream deflector 2 is communicated with chimney 11, and cooking stove casing 3 is bearing on the cooking stove pin 12.The hole that honeycomb briquette is put in combustion chamber 5 refractory material manufacturing, the endoporus of combustion chamber 5 is circular, and outer wall is square.Square ring-type vaporization cover 4 is sleeved on the square outer wall top of combustion chamber 5, and vaporization cover 4 and combustion chamber 5 outer walls are square, have strengthened heat transfer area, and the water vapor amount in the vaporization cover is increased.Vaporization cover 4 is connected with water inlet pipe 10 and steam delivery tube 6 respectively, and snorkel 6 is connected with steam jet pipe 8 in the cooking stove bottom.8 pairs of small ovens of steam jet pipe only get final product with single hose, the jetted hole 13 that to have a diameter in the steam jet pipe exit be 1.5mm, for large-scale coal stove, the two annulus tubular types of steam jet pipe 8 usefulness, on each ring tube, have jetted hole 13, open four jetted holes 13 on the interior ring tube, open eight jetted holes 13 on the cylindrical endless tube, the aperture is 0.6 millimeter.Jetted hole 13 is over against the coal hole of honeycomb briquette.

Filled heat insulating material such as expanded perlite or aluminosilicate refractory fiber (cotton) etc. between combustion chamber 5 and the cooking stove casing 3, vaporization cover 4 and cooking stove casing 3, cooktop surface can be used the stainless-steel sheet manufacturing, seem U.S. existing luxurious.Also available other material is made.

Cold water entered the vaporization cover from water inlet pipe when this coal stove used, water in the vaporization cover conducts heat through red-hot combustion chamber and heats, be heated rapidly and be vaporized into water vapour, be sent to air jet pipe through steam delivery tube, spray to red-hot honeycomb briquette hole from jetted hole, make steam and scorching hot coal-fired effect produce hydrogen and oxygen, they participate in burning, make flame more prosperous, and the nature explosion becomes fine powder when having all a part fire coal run into little water particle simultaneously, participate in burning rapidly, under jet-stream wind constantly acted on, combustion flame was more and more prosperous, and water coal for mixing combustion effect is become better and better, flame is gone out higher to boiler face, reached the effect of efficient combustion-supporting.
