Description

Energy-efficient hot water heating stove

(1) technical field: the utility model relates to a kind of energy-efficient hot water heating stove, belongs to the heating and energy saving technical field.

(2) background technology: present general coal burning water heating heating stove, the heat exchange area of cigarette G﹠W is little, exhanst gas outlet temperature height, the hot water outlet temperature is low, and waste of fuel is big, and the thermal efficiency is low.

(3) the purpose of this utility model provides a kind of energy-efficient hot water heating stove, the thermal efficiency is improved greatly, structure of the present utility model is shown in Fig. 1-2, heating stove has the furnace shell (4) of metal tubular construction, furnace cavity is divided into three zones, be heat transfer zone XZ, combustion zone CZ and dust stratification district AZ, heat transfer zone and combustion zone are double-deck furnace shell, dust stratification district one deck furnace shell, give hot interlayer (6) between double-deck furnace shell, courage (12) is hung in annular little heating of inclining that the heat transfer zone that is positioned at furnace head has seamless steel pipe to curve, hang courage (12) have logical give thermal jacket (6) give hot water inlet pipe (13) and logical burner ring-shaped water jacket add hot water outlet pipe (5), heating is hung courage (12) and is the low dip shape in the space, a little higher than hot water inlet pipe's (13) one sides of giving of hot water outlet pipe's (5) one sides; The square logical heating tube (15) that gives hot water jacket (16) that one or more is arranged under the courage (12) is hung in heating, also is the low dip shape and arranges.Furnace head has smoke evacuation tube (1), and the heat exchange fin (2) of evenly arranging is arranged on its barrel; The furnace head annular space has hot water outlet (3); There is refractory lining (8) the double-deck furnace shell inboard of combustion zone CZ, middle space one side has coal filling hole to be opened/closed (7), and bottom, combustion zone one side has backwater, cold water inlet, is dust stratification district AZ below the fire grate (9), ash door to be opened/closed (11) is arranged, and adjustable air door (13) is arranged.

During use, cold water or recirculated water enter from inlet (10) and give thermal jacket (6), heat through absorbing refractory lining (8) gives heat with water, upwards enter little heating of inclining and hang courage (12) and be bent into,, conduct heat soon with direct flue gas heating with seamless steel pipe from jacket water (J.W.) import (13), non-leakage, durable in use, enter the burner annular space from the water that hangs gallbladder-heat water out (5) outflow, flow to heating system from furnace head hot water outlet (3) again.Heating tube (15) is also used heat resisting pipe.

The utility model and this kind of correlation technique comparison product are exclusively used in heating, and thorax top is little inclines and hang the courage heat absorption, reduces exhaust gas temperature, and its specificity and compatibility comparison are more economized on coal, and leaving water temperature is higher, and heating effect is better, and the type of furnace is reasonable in design, and Natural Circulation speed is fast.Because the design has adopted the courage that hangs that seamless steel pipe curves, seamless steel pipe, no weld seam, no sand holes can not seep water, and long service life is fit to small size Home Heating usefulness, and is economical and practical, easy to use.

(4) description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 hangs the courage stereogram for little heating of inclining of the present utility model.

(5) specific embodiment: referring to accompanying drawing 1 and Fig. 2.

The welding of shell steel plate, make the combustion zone of giving thermal jacket and strap clamp cover dust stratification district not, the fire grate foundry goods, furnace chamber hangs courage and bends to annular with seamless steel pipe, both sides have gives hot water inlet pipe (13) and adds hot water outlet pipe (5), give the logical thermal jacket (6) that gives of hot water inlet pipe, another adds the logical furnace head ring-shaped water jacket of hot water outlet (5).Heating tube (15) is made with heat resisting pipe, and two ends lead to into gives thermal jacket, also is the low dip shape in the space and installs.
