Abstract

The utility model relates to a cyclone coal-fired stove hearth, comprising a wall body 1. The utility model is characterized in that a plurality of through-holes 4 are arranged in the wall body 1. The upper ends of the through-holes 4 are provided with upper air inlets 2, and the lower ends of the through-holes 4 are provided with lower air outlets 3. The upper air inlets 2 and the lower air outlets 3 are arranged on one side of the inner cavity of the wall body 1. The utility model is used for changing a combustion mechanism in the coal-fired stove to a circulating air inlet combustion mechanism which forms cyclone combustion. Thus, the oxygen inlet amount can be increased, and the combustion area temperature can be raised. Various combustion components can be fully burned, and energy loss and pollution can be decreased.

Description

Cyclone coal-fired stove hearth

The utility model belongs to field of combustion technology, refers to a kind of coal-fired combustion chamber that forms turbulent flow, burns repeatedly that makes in the combustion chamber especially.

Since using coal stove from the mankind, just exist poor efficiency and problem of environmental pollution, coal accounts for 70% greatly in the fuel of China, nearest Beijing and Shenyang also are listed in two in the seven big severe contamination cities, the world, in order to address the above problem, people have carried out various researchs, and relative measures proposed, but solve a problem often and brought other problem again, for example Chang Yong F.D has increased the oxygen supply amount, fuel can be burnt more fully, but power consumption and heat energy and unburnt carbon monoxide extraly, flue dust also spills into the space thereupon, has increased the pollution of atmosphere.

Goal of the invention of the present utility model is the combustion chamber that discloses a kind of coal stove, and it has the stove of change internal combustion mechanism, realizes energy-conservation, as to reduce pollution effect.

Realize that technical solution of the present utility model is as follows: this combustion chamber comprises wall body 1, its key is to be provided with many through holes 4 in the wall body 1, the upper end open of through hole 4 is last air inlet 2, and the lower ending opening of through hole 4 is following air outlet 3, and last air inlet 2 and following air outlet 3 are positioned at inner chamber one side of wall body 1.

Utilize the utility model, when moulded coal during in the burner hearth internal combustion, the burning of moulded coal upper surface, wind enters from the moulded coal below, enter the top burning of coal, the part of high-temperature gas enters the last air inlet 2 on the wall body, and from air outlet 3 effusions down, the combustion zone then forms small negative pressuren zone by through hole 4, and make the combustion zone form the turbulent combustion district, this impels the air intake of moulded coal below more rapid, increases intake, and the hot gas that will descend air outlet 3 to overflow in the time of air intake again is mixed into the combustion zone, this makes burning more strong, ignition temperature is higher, makes the abundant after-flames of combustible component such as carbon monoxide, has also widened combustion range simultaneously, utilize this combustion chamber, the multiple low calorie fuels that can burn, as gangue, the straw in rural area etc.Utilize the utility model, combustion zone temperature can reach 900 ℃, near high desulfurization rate temperature (950 ℃), helps reducing the pollution of sulphur to atmosphere.

Provide structure of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1;

Fig. 4 is used for the enforcement figure of stove and accessory for the utility model.

Referring to Fig. 1-Fig. 4, concrete structure of the present utility model is as follows: the utility model comprises wall body 1, its key is to be provided with many through holes 4 in the wall body 1, the upper end open of through hole 4 is last air inlet 2, the lower ending opening of through hole 4 is following air outlet 3, and last air inlet 2 and following air outlet 3 are positioned at inner chamber one side of wall body 1; Described wall body 1 is a tabular, when wall body is the two sides of stove and accessory, its moulded coal 7 is located between the wall body 1, moulded coal below air intake, the burning of moulded coal top forms the high-temperature region, because the last air inlet 2 on the wall body 1 is positioned at the high-temperature region, be significantly less than the air inflow of moulded coal below because of blast pipe 8 gas outputs, then force high-temperature gas to enter air inlet 2, mix entering moulded coal again by through hole 4 from following air outlet 3 effusions and with live gas, unburnt gas is burnt again.

Described through hole 4 forms an angle with the vertical line of wall body 1.

Be respectively equipped with outer air inlet 5 and the outer air inlet 6 down gone up on the outside wall surface of described wall body 1, this two air inlet communicates with through hole 4, then can be from stove and accessory outside air intake, to increase oxygen feeding amount during burning.

Described wall body 1 is a ring-type, both ends open up and down, and it can be used for various small-sized stove and accessorys.

Utilize above-mentioned utility model, make combustion mechanism change the circulation charge combustion into, form the cyclone type burning, it helps to increase oxygen feeding amount, improves combustion zone temperature, makes the abundant after-flame of various flammable compositions, reduces energy loss and pollution.
