Description

The moulded coal water heater

Technical field

The utility model relates to a kind of hot water coal stove, the moulded coal water heater that especially a kind of fuel is bulk or honeycomb briquet.

Background technology

Existing moulded coal water heater, after the moulded coal burning, need to wash in a pan except that coal ash with the scum hook, with scoop coal ash is scooped up away again, stoking is to drop on the fire door that opens wide, this can cause and stir up a cloud of dust, pollute indoor air and environment, increase the amount of labour simultaneously, unlimited fire door also can cause a large amount of loss of heat energy.

China's utility model patent 200620117553.6 discloses a kind of " coal burning water heating range ", it is a combustion chamber bottom deslagging honeycomb briquette stove, this stove adopts movable grate, after cutting off cinder, cutting knife on the grate falls among the ash bucket under the grate, stoking is that a stoking door opening the stove shell carries out, though this structure has partly solved the problem of dust pollution and heat-energy losses.But still there is following shortcoming: 1, can only burn honeycomb briquet, be not suitable for other block moulded coals; The moulded coal burnout rate is not high, and the furnace height of honeycomb briquette stove generally is designed to three～four honeycomb briquette height, and like this, often lowermost coal cinder does not burn cinder as yet, and firepower is inadequate, must change new coal cinder.2, honeycomb briquet coal briquette size is restricted, and the process of burning is short, and is clearance-type, and the furnace temperature constancy is poor, uses easily to produce bigger temperature fluctuation on the heat hot water tank, and large-scale hot-water cooking stove is not suitable for; 3, slag dumping is mechanically shovel cut-out, and the moulded coal pinkeye is stopped up, and causes inefficient combustion; 4, aquifer yield is less.

Summary of the invention

Technical problem to be solved in the utility model provides that a kind of moulded coal combustion heat loss is little, the heat utilization ratio height of flue gas, and the heat production water yield is big, the moulded coal water heater of slagging-off residue-discharge convenience.Not only honeycomb briquette can be burnt but also can burn moulded coals such as coal briquette, and the contaminated environment that stirs up a cloud of dust can be significantly reduced.

Concrete scheme of the present utility model is that prior art honeycomb briquette coal burning water heating range is improved, a kind of moulded coal water heater, and it is divided into upper and lower two sections, and epimere is a main water box, establishes water inlet and delivery port (3) on the casing; Combuster, burner hearth in the hypomere body of heater; Between combustion chamber, burner hearth and body of heater shell, a preheating water tank is arranged, also establish water inlet and delivery port on the preheating water tank; This delivery port has pipeline to be connected with the main water box water inlet; Have in the main water box with burner hearth in the hypomere body of heater to be connected, and lead to the flue gas heat exchange device of main water box top smoke pipe; On the corresponding body of heater shell of above-mentioned burner hearth a stoking door that communicates is with it arranged; The grate of being made up of the parallel laying of movable fire bars of many shaft band chaste tree ratchets is equipped with in below, above-mentioned combustion chamber; The below of grate is an air compartment, air compartment peripheral hardware fire door.

Further, the above-mentioned built-in slag dolly that connects of air compartment; When the demand hot water amount was big, the utility model can be established the air blast interface in above-mentioned preheating water tank's bottom, was used to connect air blast and improved firepower.

When the utility model need change coal, directly open the stoking door, moulded coal is dropped into the combustion chamber get final product; To the no specific (special) requirements of type coal shape size, do not need the hole, not only honeycomb briquette can be burnt but also moulded coal such as coal briquette can be burnt.Close the stoking door after stoking is finished, help reducing the burner hearth thermal loss, improve the heat utilization ratio of flue gas.The moulded coal slag that burns, as long as by operating the movable fire bars of swing handle rotating band chaste tree ratchet, the chaste tree ratchet rolls mutually between the fire bars in twos, can with burn cinder the coal cinder crushing fall in the slag dolly of air compartment, open fire door, haul out the slag dolly and just can carry out slag removal, very convenient.And in operating process, the stoking door is closed, overcome effectively that prior art exists go out slag the time cause cinder to fly upward easily and influence the healthy deficiency of people, have characteristics such as simple in structure, novel in design, easy to use.Because there is the flue gas heat exchange device burner hearth of the present utility model top, high-temperature flue gas is through the flue gas heat exchange device, and heat is directly passed to water in the main water box, further improves the heat utilization ratio of flue gas, reaches the hot water purpose fast that heats up.

Compared with prior art, the utility model aquifer yield is big, and the hot water supply is stabilized in 30-200 ton/sky, except that being used for productive life hot water, can also be used for air-conditioning heating; The utility model changes coal does not need mobile coal stove, and the operating space only needs 2-3 square metre, the actual measurement thermal efficiency up to 90%, have simple to operate, the operating space is little, safe in utilization, thermal efficiency height, characteristics such as environmentally-friendly sanitary.
