Abstract

The utility model relates to a complete stainless steel high-efficiency coal furnace for heating water which can completely use the fume waste heat through a waste heat chamber arranged on the outer wall of a water jacket, simultaneously the water temperature of the water jacket can slowly increase under the fire sealing condition. The heat insulation around a furnace hearth can be thickened due to the effect of the waste heat chamber, the temperature holding method is also adopted around an ash chamber, thereby the fire increasing speed can be increased, and the fuel can be completely combusted. An automatic air discharging device adopts a thermal recycling method. The steam produced from the water jacket can be automatically discharged; the water temperature at the upper side and the lower side of the water jacket can be maintained basically to be uniform; additionally the installation of a safety valve causes the operation absolutely safe and reliable. Because the waste heat chamber, a flue elbow and a smoke tube can form a complete flue to make the room free from coal gas, the thermal efficiency can reach up to more than 70 percent.

Description

The efficient hot water coal stove of all steel

The utility model belongs to a kind of life appliance.

Present existing hot water coal stove is made up of water jacket, burner hearth, grey chamber, body of heater etc.This class hot water coal stove 1, since burner hearth around heat-insulation layer too thin, coal can not get abundant burning.2, automatic exhaust device and employing thermal cycle measure are not installed, water temperature difference is apart from too big up and down to cause water jacket, and safety can not get guarantee simultaneously.3, fume afterheat does not make full use of.Below all be unfavorable for heat energy utilization, environmental pollution also has certain influence simultaneously, and the thermal efficiency is generally all below 50%.

The purpose of this utility model provide a kind of all steel, energy-efficient, the speed of getting angry is fast, firepower is vigorous, hot water many (Duoing more than one times than general hot water coal stove), and has an automatic vent and water jacket advantage of water temperature basically identical up and down, it is reliable to be perfectly safe during use, indoor no coal gas, the thermal efficiency is up to the novel hot water coal stove more than 70%.

The purpose of this utility model is achieved in that it is by formations such as body of heater, boiler face, burner hearth, heat-insulation layer A, heat-insulation layer B, water jacket, the outdoor cover of waste heat, waste heat chamber, smoke canal elbow, grey chamber, water valve, bell A, bell B, thermal cycle A pipe, thermal cycle B pipe, automatic exhaust device (comprising exhaust nozzle, outer wall, vapour inlet, cylindrical ball float), safety valve, water inlet pipe, hot water delivery pipes.

Characteristics of the present utility model are:

1, owing to be provided with the waste heat chamber around the water jacket, can effectively utilize waste heat, could thicken burner hearth heat-insulation layer on every side, add that grey chamber also adopted the insulation measure on every side; The insulation of so grey chamber can preheated air, and the air of preheating enters in the burner hearth, can reduce the influence of cold air to furnace temperature, helps burning.Adopt thicker heat-insulation layer around the burner hearth, can effectively improve furnace temperature, more help burning.Therefore double action owing to burner hearth and grey chamber adopt the insulation measure to produce equally, can be fully burned coal, reaches the vigorous and fireballing purpose of getting angry of firepower.

2, because water jacket is provided with the effect of waste heat chamber on every side, and make water jacket inwall, outer wall and top can both become heating surface, increased the heating surface area of water jacket greatly, so waste heat energy is fully used.On the other hand, the hot cell also has certain temperature because the situation of banking up a fire is left, and the area of water jacket 90% places waste heat indoor again, and the hot water in the water jacket not only can not reduce water temperature like this, can also improve certain temperature on the contrary.More than two be the principal element that water jacket has more hot water, so can reach the purpose that has more hot water more than one times than general hot water coal stove.

3, automatic exhaust device is made up of exhaust nozzle, outer wall, vapour inlet, cylindrical ball float.If the water in the water jacket produces steam, the water level in the water jacket must descend, and ball float also just descends thereupon, and the steam that water jacket produced enters exhaust nozzle by vapour inlet, discharges to atmosphere through exhaust nozzle.Because the minimizing of water jacket inner vapor, ball float can rise again naturally, directly causes ball float top valve rubber and blocks till the exhaust nozzle.Operation can reach self-bleeding purpose so repeatedly.Solved simultaneously because of water jacket produces steam, and the hot water in the compressing water jacket by under cause and return the water source, and cause the waste of heat energy.More help safety in addition.The utility model has also adopted safety valve for guaranteeing safety.

4, thermal cycle is made up of thermal cycle A pipe and thermal cycle B pipe.Water jacket divides two-layer up and down, adopts the thermal cycle principle, and the water of water jacket lower floor lowest part enters water jacket upper strata lowest part (annotate: during water, water jacket upper water programming rate is fast) through thermal cycle B pipe.After heating up, high-temperature water enters water jacket lower floor by water jacket upper strata highest point through thermal cycle A pipe and (annotates: 1/3 place from the bottom to top).Move so repeatedly, can reach the purpose of the water temperature basically identical of whole water jacket.

Above-mentioned four have all been play a part in various degree heat energy utilization, therefore can reach the thermal efficiency 70% the above object.

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