Abstract

The utility model relates to a reverse burning smoke eliminating energy-saving drinking boiler. The lower part of a water cooling fire grate is provided with a combustion chamber, and the upper part of a water cooling fire grate is lined with refractory material to protect the fire grate. A coaling chamber comprises a plurality of flow pipes and refractory material. Reverse burning of coal results in volatile combustible gas passing a coal bed to burn out to achieve the effect of smoke eliminating. The utility model has the advantages of smoke eliminating, energy saving, heating collection, steaming and bathing by means of water circulation. Besides, the utility model has multiple functions.

Description

Reverse burning smoke eliminating energy-saving drinking boiler

The utility model relates to a kind of water boiler, be can drink water and can steamed rice, the normal-pressure boiler of having a bath.

The fuel major part used of water boiler is fragmentary bituminous coal for many years, and the many dirt of cigarette are many during work, and environment is caused very big pollution, for this reason people to attempt to design a kind of be energy savings water boiler free from environmental pollution again.As the boiler with two-layer fire grates of selling on the present market, form by cylinder, inner furnace, water cooling tube upper fire-grating, cast iron lower fire grating etc.Operate by operation instructions if this water boiler is strict, can make in the anti-burning process combustible is burnouted, can eliminate the pollution of black smoke environment.But the general operation personnel for convenience, only burns lower combustion chamber, lost the effect of double-layer grate.

For addressing the above problem, the utility model provides a kind of new type drinking water boiler

The purpose of this utility model provides a kind of backfire water boiler that has only one deck fire grate.

It is the backfire water boiler that has refractory material that another purpose of the present utility model provides a kind of water-cooled grate.

The purpose of this utility model is to realize like this, lower floor's casting furnace grate of former double-layer grate is removed, only keep the top water-cooled grate, but the gap of water-cooled grate is reduced to 8-15mm the both sides of water-cooled grate are added two blocks of heat resisting steel laths of weldering, top at water-cooled grate is lined with refractory concrete, makes upper fire-grating be plane, and coal is when burning like this, make underseam temperature high combustion complete, the combustible that volatilizees when giving hot charing of day-coal has played the purpose that eliminates smoke by burning zone in addition.The combustion chamber of one long round body being set in the bottom of water-cooled grate, being provided with several fire tubes on the top of coal chamber, is heat gathering box and flue on the top of fire tube.

The utility model is because only need on former double-layer grate water boiler basis, water-cooled grate is added one deck refractory material, with remove lower floor's casting furnace grate, fire door in the middle of removing, make technology simpler, but smoke elimination and purpose of energy saving have also been played, in addition because of having only a fire door simple to operate, safe and reliable.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Accompanying drawing is the cutaway view of the backfire fume-eliminating energy-saving water boiler pointed out according to the utility model.

The details and the working condition of the water boiler of pointing out according to the utility model below in conjunction with description of drawings.

This stove comprises a cleanout door (1), the bottom is that flue (2) is combustion chamber (3) at the core of flue (2) in the main body, the top of combustion chamber (3) is divided into the water-cooled grate (4) that has refractory material, the top of water-cooled grate (4) is coal chamber (5), coal chamber (5) is crossed water pipe (7) by some and is formed, the centre of crossing water pipe (7) has expansion oplate and refractory concrete to seal, and must not connect with top fire tube (11).Because this structure is thrown earlier coal and given heat on the upper strata of coal chamber (5), the fuel gas that gives volatilization when hot falls through burning zone is burned.In order to improve the ignition temperature of coal bottom, increased refractory concrete (17) on the top of cold water fire grate, so not only improve the bottom ignition temperature but also protected water-cooled grate.The high-temperature gas completely that burns is compiled through fire tube (11) and heat-collecting box (12) by both sides along the direction of arrow and to enter chimney.(8) be ash removing opening, chew for water (9), and (10) are thermometer, and (13) are external furnace body, and (14) are safety valve, and (15) are vapor opening, and (16) are the water level meter, and (18) are mudhole.

The utility model heating surface area is big, thermal efficiency height, and free from environmental pollution and can water circulation heating, steamed rice, multi-use such as have a bath.
