Description

The Multifunction coal furnace

The utility model belongs to the HVAC equipment, mainly refers to a kind of multifunction burning coal stove that family and catering trade are used that is suitable for.

Existing residential coal combustion hot-water heating stove mostly is water-filling interlayer body of heater and connects water-filling interlayer chimney structure form, external radiator, and the hot-water heating heat supply, its weak point is, and it is insufficient to burn, and it is undesirable to give heat utilization, and the thermal efficiency is not high, function singleness.

The goal of the invention of the utility model is to overcome the deficiency of prior art, and a kind of Multifunction coal furnace is provided, its burning fully, it is abundant to give heat utilization, thermal efficiency height, water, vapour cycle are reasonable, function is many, does not have the safety of pressure.

The utility model is so to implement, the Multifunction coal furnace comprises body of heater, the chimney that joins, wraps up in the interlayer water tank of body of heater, the interlayer water tank of wrapping up in chimney and heat-insulation layer and all parts of shell, is characterised in that, around flue fire door cofferdam (6) suitable for reading, its section profile approximate trapezoid; Interlayer water tank (9) and (12) split setting, under the two by water pipe (23) UNICOM, on the two by steam pipe (13) UNICOM; Chimney curve place becomes falling dust room (17), have in it with interlayer water tank (12) bottom connection give heat pipe (18).

Preferred version of the present utility model is that fire door cofferdam (6) has preceding breach (22), and is the hollow cavity of metal material, interior water-filling; Interlayer water tank (12) top steam chest is established tabula (25); UNICOM's steam pipe (13) places in the chimney (16); The heat pipe (18) that gives in the falling dust room (17) is many vertical ducts, perhaps, is spiral coil.
