Description

Atmospheric hot-water boiler

The utility model relates to a kind of vapour and helps normal-pressure hot-water boiler.

At present, the most of miniature boilers of China all are to adopt double-layer grate burning and semi-coal gas to burn, and these boilers reflect the energy consumption height in running, and the thermal efficiency is low, and poor safety performance is easy to operate and smoke medicining dust-removing effect is poor, disadvantages such as manufacturing cost height.

The purpose of this utility model solves the deficiencies in the prior art exactly, and a kind of structure uniqueness, safe and reliable is provided, easy operating, and low cost of manufacture, not only energy-conservation but also vapour smoke abatement and dust control helps normal-pressure hot-water boiler.

In conjunction with the accompanying drawings concrete structure of the present utility model is being described in detail down.

As shown in drawings, the utility model vapour helps normal-pressure hot-water boiler mainly to be made up of body of heater 15, flue 14, drum 18, nozzle 28, economizer 20, deduster 21, blower fan 1 etc. Body of heater 15 is cylindrical, and the bottom that furnace roof 17 is provided with exhaust outlet 19, body of heater 15 is air compartment, and the circle 6 of getting a foothold is equipped with in the air compartment bottom, and the shell of body of heater 15 is provided with slag door 8, fire door 11, ash door 13 and water gage 25. Flue 14 is located in the body of heater 15, between the air compartment of flue 14 and body of heater 15 fire grate 5 is housed, and the bottom of flue 14 is the combustion chamber. For guaranteeing the ignition temperature in the stove, the high topped bake oven of tilting is adopted in the combustion chamber of this stove, and this bake oven is made up of union 10, header 7 and flame retardant coating 9. Header 7 is fixedly mounted on the flue 14, and 7 of flue 14 and headers are equipped with union 10, and the outer surface of union 10 is topped flame retardant coating 9. The angle of union 10 and body of heater 15 axis＞90 °. Steam generator 12 is located at the top of flue 14, and the water inlet of steam generator 12 passes body of heater 15 and links to each other with the outlet pipe of economizer 20, and the delivery port of steam generator 12 links to each other with drum 18. For making not pressure-bearing of drum 18, be provided with vapour union 16 at drum 18, an end of vapour union 16 communicates with drum 18, and the other end passes in the stove water. Guarantee drum 18 non-pressure bearing operations, can with the steam pipe oven water of discharging, reduce thermal loss again. Water and stove water in the steam generator 12 do not circulate mutually, and water capacity is few, and heating surface is big, and it is fast to steam. The steam that steam generator 12 produces, by drum 18, vapour union 26 and help steam valve 27 to lead to the top of combustion chamber, spray micro-saturation type superheated steam at a high speed through special narrow nozzle 28, the moving flue gas rotates in upper furnace, increases the time of staying of flue gas in burner hearth, produces complicated physics and chemical change, accelerate the chemical reaction velocity of combustible and gas, overheavy firing, the maximum heat that effectively discharges fuel reaches abundant completing combustion. The flue gas trend is two backhauls, through economizing coal mouth 20, deduster 21, chimney 22 discharge atmosphere, because flue gas is through deduster 21, can be with the heating of the water in the water jacket in the deduster 21, take full advantage of the waste heat of boiler, improve the thermal efficiency of boiler, played energy-conservation, smoke abatement and dust control, reduced the effect of blackness of exhaustion. Economize coal Mouthfuls 20 are contained in the exhaust opening of body of heater 15 and advancing between the mouth of deduster 21, and economizer 20 is made by cast iron materials, and the top of economizer 20 is water tank, is provided with ball-cock assembly 23 in the water tank. Help an end of steam pipe 26 to be connected with drum 18, the other end is by helping steam valve 27 to be connected with nozzle 28, one end of induced duct 24 communicates with chimney 22, the other end links to each other with threeway, other two ends of threeway, one end links to each other with the outlet of blower fan 1, and the other end links to each other with the air compartment of body of heater 15 by blast pipe 3, adjusting valve 4. Simultaneously boiler of feeding air blast of blower fan 1 and injection air can be regulated air quantity at any time by adjusting valve 4, guarantee the normal combustion of boiler, again not pressure combustion.

The utility model can according to user's needs, be made series of products.

The utility model is compared with the semi-coal gas burning boiler with traditional double-layer grate burning, energy-conservation 10-15%, and the thermal efficiency reaches 78%, smoke abatement and dust control reaches or less than a national class regional standard, the while low cost of manufacture, steel consumption reduces 40-60% than conventional boiler, remarkable in economical benefits.This boiler pressure in running is 0 and safe and reliable forever, long service life.Can be widely used in factories and miness, enterprise, office, school and service industry's heating, the use of having a bath, drink water.
