Abstract

The utility model relates to an internal combustion external burning upright normal pressure environmental protection and energy-saving water heating boiler used solid fuel as heat source for heating, showering, cooking and supplying boiled water. The utility model is characterized in that two secondary wind pipes(9) with different angles and adjustable position are provided; an upper ceiling pipe (20) is provided with a hearth, and a fire baffle plate (17) added at the middle of a longitudinal water pipe (15); the fire baffle plate divides the hearth into two smoke channels(14)(16); the smoke passing across a settling chamber enters a rotary smoke channel (6) out of the boiler by an inverse smoke opening (19) and is exhausted from a chimney outlet. The utility model has advantages of energy saving, thoroughly burning of the secondary wind fuel, internal combustion external burning, a heated surface changed from the heat delivery surface of the original boiler shell, improved boiler heat efficiency, and lower temperature in exhausting smoke, furthermore, environment protection, long internal combustion external burning process, good elimination smoke and dust effect by the centrifugal settling of the rotary smoke channel, small ground occupying, convenient installation and low operation cost, without an airing apparatus helping.

Description

The vertical atmospheric hot-water environmetnal protection power economized boiler of the outer burning of internal combustion

Technical field

The utility model relates to the normal-pressure hot-water boiler of vertical heating, bathing, steamed rice, supply boiling water.

Technical background

Present improving constantly along with living standards of the people, the use of minitype vertical type normal-pressure hot-water boiler more and more widely, but because common vertical boiler majority is that single backhaul directly connects with chimney, have following shortcoming: the flue gas stroke is short, flue gas resistance is little, exhaust gas temperature is high, the little deficiency in draught burning of grate area is not thorough, over-emitting black exhaust, and carbon monoxide particle and dust that some do not burn directly enter atmosphere, not only energy utilization rate is low wastes energy, and environmental pollution is serious.

Summary of the invention

The purpose of this utility model solves above-mentioned existing problems and designs.

The utility model is achieved in that at first flame concentrates the place to establish two adjustable secondary air channels (9) above burner hearth,

Unburned combustible is fully burnt, to solve the deficiency in draught problem by the secondary air feed.In stove, add engine firewall (17) in the middle of canopy pipe (20) and the middle drainpipe (15), stove inner flue separated into two parts (14,16) is established expansion chamber (18) and anti-burner (19) in two flues (16) bottom, flue gas enters stove inner rotary flue (6) by anti-burner (19) after sedimentation, and then discharges by chimney (5).The prolong smoke flow process reduces exhaust gas temperature, improves boiler efficiency.

Description of drawings

Accompanying drawing 1 is that front view comprises exhaust fitting (1), deashing inspection socket (2), thermometer joint (3), hot water outlet (4), chimney breast (5), stove inner rotary flue (6), boiler jacket (7), smoke baffle plate (8), adjustable secondary air channel (9), upper and lower fire door (10), sewage draining exit joint (11), ash door (12), backwater inlet (13).Water level meter (23)

Fig. 2 is a vertical view: Fig. 3 is a sectional elevation: a flue (14), water pipe (15), two flues (16), engine firewall (17), expansion chamber (18), anti-burner (19), canopy pipe (20), water bar (21), fixed grate (22).

Specific embodiments

One, adopt the secondary air channel (9) of 15 degree and two different angles of 35 degree and position to be arranged on the burner hearth back upper place, utilize the draft of chimney with the suction of secondary wind during the stove operation, because the difference of ventilation angle and position forms vortex, the fuel gas that does not burn with anoxic mixes, make the abundant mixed combustion of unburnt gas, promptly reach energy-conservation purpose and reduced the discharging of black smoke, solved vertical boiler deficiency in draught problem.

Two, add engine firewall (17) in the middle of interior upward canopy pipe (20) of stove and the horizontal water tube (15) and will be divided into two flues (14,16) in the burner hearth, the prolong smoke flow process, augmentation of heat transfer improves the heat exchange effect, reaches energy-conservation purpose; Locate to establish expansion chamber (18) at the anti-burners of two flues (16) (19), go out clearly by cleaning door after the bigger ash fall of particle, reduce solid discharge capacity in the flue gas, help environmental protection.

Three, after flue gas enters shell external flue (6) by anti-burner (19), under the effect of smoke baffle plate (8), the flue gas rotation is risen and is entered chimney.

Its advantage has two aspects:

(1) energy savings: boiler utilizes fume afterheat by outer burning of internal combustion, with the radiating surface of common vertical boiler housing parts, changes into heating surface, has promptly utilized waste heat fully, and has reduced exhaust gas temperature, has improved boiler efficiency.

(2) environmental: as, under the effect of smoke baffle plate, to rotate rising and enters chimney when flue gas enters external flue by anti-burner at two flues (16) behind expansion chamber (18).Most of dust is deposited in the external flue bottom once more under rotation rising centrifugation effect in this process, goes out clearly by cleaning door (2), to reach the environmental purpose of smoke abatement and dust control.

Four, easy to install, without forced-and-induced draft fan and cleaner, operating cost is low.

Five, the utility model also is applicable to other individual layer fire grate vertical boiler.

Claims (4)
