CN2604436Y - Abnormal-hole, fluted energy-saving honeycomb coal - Google Patents

Abstract

The utility model relates to an irregular-hole concave channel of energy-saving honeycombed coal at one end plane of which is equipped a sunk compartment and a vent channel which faces toward the centre. At the centre of the vertically arranged honeycombed coal is a large fire hole around which is equipped a small fire hole. In case of service, three to four honeycombed coals are stacked in an oven to leave a sunk combustion chamber between the honeycombed coal. Besides an upward ventilation, the lateral air can flow into the sunk compartment by an ventilation channel, which can be beneficial to a firepower concentration and a quick and complete combustion. The utility model is characterized by lower coal consumption, quick fire spread, strong firepower, little pollution, convenient operation and easy popularization.

Description

Different hole groove energy saving briquette

The utility model relates to a kind of honeycomb briquette.

Traditional honeycomb briquette is the cylinder type of the vertical fire hole that gathers.During use, be arranged in the fire hole of burner hearth honeycomb briquette and must consistency from top to bottom oxygen could run through and enter fire coal and help so from burner hearth bottom.The diameter of all fire holes equates on the other hand, is unfavorable for the smooth and easy burning of coal and concentrating of firepower.Simultaneously, traditional honeycomb briquette speed of getting angry is slow, and a little less than the firepower, combustion exhaust gas is big, it is comparatively serious to pollute.Though I have following advantage by the Qu Bianyi hole concave-concave energy-saving coal of original invention, complex process, yield rate is lower.

The purpose of this utility model is a kind of different hole of design groove energy saving briquette, makes it have province's coal, and the speed of getting angry is fast, and firepower is concentrated, sufficient combustion, less contamination and the convenient advantage of using.

One end face of the utility model honeycomb briquette is provided with a concave surface chamber, and is provided with ventilation slot at its same end face to the center, and the vertical center of distribution of moulded coal is provided with a big fire hole, and vertical fire hole such as is at big small fire hole around the big fire hole.The said structure design has realized the purpose of this utility model.

The consumption that the utility model has the advantages that coal only accounts for measure-alike legacy cellular coal coal consumption 5/6ths, and identical piece number gets angry than legacy cellular coal that speed is fast, firepower is strong, can fully burn, the no black coal slag in burning back.Because this coal piece of getting angry, sufficient combustion, during burning smoke evacuation little, firepower is concentrated, the less contamination environment, and be easy to make produce, cost is low, heat utilization efficiency is high, simultaneously, the convenient use do not bother and aims at fire hole up and down, so be easy to promote.

Below in conjunction with Figure of description the utility model structure is further described.

Fig. 1 is the utility model synoptic diagram.

Fig. 2 is the A-A diagrammatic cross-section of Fig. 1.

As depicted in figs. 1 and 2, loop wire 2 is the sideline of this honeycomb briquette alcove, and 1 is its side, is provided with an alcove 4 at its end face, and alcove should be inwardly recessed apart from a peripheral segment distance, connects and guarantees its hardness to guarantee that up and down two honeycomb briquette faces are beneficial to.At honeycomb briquette the same end of alcove is arranged, laterally be provided with ventilation slot 5 to the center, its effect is to be beneficial to alcove competent convection current air is provided, and is beneficial to alcove and fully exchanges heat and air, homogeneous combustion with the honeycomb briquette edge.Ventilation slot can be established the 4-8 bar according to situation.Be provided with a big fire hole 6 at the vertical center of this honeycomb briquette, the big fire bore dia can be 1.5-2.5 centimetre, vertical fire hole around the big fire hole is a small fire hole 3, and the small fire hole diameter is 1-1.4 centimetre, and the ventilation slot end face preferably connects big fire hole periphery and is beneficial to convection of air.During making, ventilation slot, big fire hole, small fire hole and concave surface chamber can be positioned at the mould last time and be stamped to form.During use, the 3-4 piece is superimposed upon in the burner hearth, forms a matrix combustion chamber between per two, and big or small fire hole and the periphery of honeycomb briquette this matrix combustion chamber that all communicates is not no matter so whether the consistency from top to bottom fire hole all influences moulded coal does not fully burn.

In a word, the utility model get angry piece, firepower violent, burn thoroughly, less contamination, economize on coal, the heat utilization efficiency height, easy to use is a kind of substitute products of legacy cellular coal.

Claims (2)

1, a kind of different hole groove energy saving briquette, formed by the vertical small fire hole that distributes on the honeycomb briquette, an end face that it is characterized in that honeycomb briquette is provided with an alcove, and be provided with ventilation slot to alcove or coal body center at its same end face, the vertical center of distribution of honeycomb briquette is provided with a big fire hole, and the vertical fire hole around the big fire hole is a small fire hole.

2,, it is characterized in that ventilation slot connects the alcove or the center of honeycomb briquette by the described different hole of claim 1 groove energy saving briquette.
