Description

The domestic multipurpose power economized boiler

The utility model belongs to the heat supply stove, is the daily heating of a kind of family, kitchener.

Domestic boiler in the general daily life, heating-cooking separates mostly, though the multipurpose boiler that has both to be integrated, have because unreasonable structure, firepower is not concentrated during cooking, influence result of use, the more water pipe of the employing that has carries out heat exchange, not only complex structure, and the easy fouling of water pipe, cleaning difficulty uses soon that heat-transfer effect will reduce greatly, has lost the multipurpose function of boiler.

The purpose of this utility model provide a kind of simple in structure, the thermal efficiency is high, both can be used as family expenses direct heat source, multipurpose power economized boiler that again can hot water heating.

The purpose of this utility model is to realize like this, the domestic multipurpose power economized boiler, comprise body of heater, burner hearth, be positioned at upper furnace the combustion chamber, and the flue that links of combustion chamber, comprise heat-exchange system that heat transfer medium is positioned at the burner hearth flue, and flue boiler, the burner that is positioned at top of combustion chamber, the fire bars that is positioned at the lower furnace portion supporting fuel, the ash bucket of depositing the combustion slag, the fire door that adds fuel and each parts that link between be connected and fixed part and work auxiliary.Wherein, heat-exchange system in the described burner hearth, contain water jacket and water inlet that heat transfer medium is positioned at the burner hearth perisporium, place the heat-conducting plate on the water jacket perisporium of combustion chamber, heat-exchange system in the described flue, contain circulating water cavity and delivery port that heat transfer medium is positioned at flue and hearth water sleeve UNICOM, place the fire tube consistent in the circulating water cavity with the flue direction, place the water service pipe of fire tube top and circulating water cavity UNICOM, described boiler, be positioned at the flue top, chimney passes water tank, inner wall of stack is established heat-conducting plate, described burner can be laid coal stove with through water, and coal stove with through water comprises housing, the ring-type water pipe is provided with the ring-type water pipe in housing, water inlet is located at the housing side, delivery port is located at the bell top, and described heat-conducting plate is the triangle steel plate, and the every limit of heat-conducting plate in the burner hearth is provided with three at least, fire tube quantity in the described flue is 2-14, and water service pipe quantity is 1-3.

The utlity model has following advantage and effect:

1, owing in burner hearth, cancelled the normal heat pipe that adopts of general multipurpose boiler, use simple heat-conducting plate instead, the size of heat-conducting plate with quantity is set, can determine according to heating area.Not only simplify the structure, and because heat-conducting plate is less scaling, it is fast to conduct heat, the thermal efficiency is high, when particularly using as direct heat source, firepower is concentrated, time-saving energy-saving.

2, owing to be provided with the fire-tube type circulating water cavity in flue, fire tube quantity can be determined according to heating area, increases fire tube quantity and can increase heat exchange area, has improved the thermal efficiency.

3, owing to the water service pipe of suitable setting above the fire tube of flue, so as to further increase heat exchange area with circulating water cavity UNICOM.

4,, can improve the operating temperature of heating medium owing to the water jacket of burner hearth perisporium and the circulating water cavity intercommunication in the flue.

5, owing to adopt the channelling water bell, when boiler during, coal stove with through water can be placed on the fire door only as heating work, not only play heat-blocking action, and utilize waste heat that warm water is provided.

Therefore, the utlity model has simple in structure, compact, the characteristics of efficient heat supply, time-saving energy-saving.
