Description

Atmospheric boiler for heating water

The utility model belongs to atmospheric hot-water boiler and makes the field.

Background technology of the present utility model is: single (two) fire grate nature smoke-eliminating stove, and the design feature of this stove is that single face turns over head, the one, the interior water circulation of stove is undesired, and boiler itself is heated inhomogeneous, influences its service life; The 2nd, nominal output does not reach (power is little), and smoke medicining dust-removing effect is not good; The 3rd, it is slow to fire speed, and heat utilization efficiency is low.

The purpose of this utility model is: avoid weak point of the prior art, design and a kind ofly two-sidedly turn over that water follows normally in the fire, stove, itself is heated evenly boiler, long service life, and it is fast to fire speed, the atmospheric hot-water boiler that heat utilization efficiency height and body are little, water capacity is big.

Design of the present utility model is: atmospheric hot-water boiler is on the basis of existing single fire grate and double grate nature smoke-eliminating stove, by a kind of two arches double combustion chamber that conceiving again of its chimney arch designed, the multistage wind structure of giving, realized that naked light and the high-temperature flue gas time of staying in burner hearth is long, the two-sided fire that turns over, make heating surface area in the body of heater big, evenly, in long, the stove of converter life the water circulation normal, quick heating, exert oneself big, heat utilization efficiency is high and boiler volume is little, water capacity is big.Organization plan is: atmospheric hot-water boiler, it comprises preheating water tank (1), square flue (2), transverse water pipe bundle (3), smoke box (4), main water box (8), communicating pipe (9), throw coal, put a chimney on the stove and make the fire draw and secondary wind adjustment doors (10) and air feed and shoot door (12), second-time burning chimney arch (6) is positioned at the below of smoke box (4) and is communicated with smoke box (4) by pyrotechnics tube bank (7), and primary combustion chimney arch (11) is positioned at secondary combustion chamber chimney arch (6).The put a chimney on the stove and make the fire draw middle part of pipeline of the convex of secondary combustion chamber chimney arch (6) is provided with tertiary air and regulates and deashing device (5).Secondary combustion chamber chimney arch (6) is the convex arch structure.Primary zone's chimney arch (11) is the reverse U shape furnace arch structure, is full of water in the reverse U shape chimney arch and is communicated with main water box (8).

The utility model is compared with background technology, the one, the two-sided fire that turns over, body of heater is heated evenly, the stove internal resistance is little, water circulation is normal, quick heating, exert oneself big; The 2nd, owing to adopt two arches double combustion chamber, the multistage wind structure of giving, it is fast to fire speed, makes burning more abundant, thereby has realized the bituminous coal smokeless combustion; The 3rd, compare with Industrial Boiler, do not need special dust seperator or smoke consuming apparatus; The 4th, compare with the double grate boiler, simple to operate, fault rate is little.The upper fire-grating pipe of double grate boiler is owing to the high-temperature region that is arranged on boiler, so very easily fouling is stopped up, and easy burn-out and difficult the replacing, and it is slow to fire speed; The 5th, compare with the double grate boiler, under the situation that volume equates, the steel quantity consumption of this stove reduces about 20%, and volume is little; The 6th, wind, smoke abatement and dust control (dust concentration 30mg/m are burnt, give naturally in the normalizing of individual layer fire grate ³About, the minimum 100mg/m of ministry standard ³Fume emission lingemann blackness 0.5, ministry standard minimum 1) not electricity consumption, noiselessness.

Description of drawings:

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

1 pair of the utility model is explained in conjunction with the accompanying drawings

The structure of secondary combustion chamber chimney arch (6) is the convex arch, the nose sealing of convex arch, and the shoulder of convex arch has the hole that several are used to weld pyrotechnics tube bank (7), and the lower end of convex arch is an Open architecture; Primary zone's chimney arch (11) is the reverse U shape chimney arch, water and be communicated with main water box (8) abrim in the reverse U shape chimney arch; The put a chimney on the stove and make the fire draw middle part of pipeline of the convex that tertiary air is regulated and deashing device is arranged on secondary combustion chamber chimney arch (6), purpose are that wind is in harmonious proportion the cleaning dust stratification.Remaining part be prior art with reference to accompanying drawing and specification the 5th part, get final product by the prior art Installation and Debugging.This stove removes preheating water tank (1) and main water box (8), and communicating pipe (9) and main water box (8) are for outside flange is connected, and remaining is Welding Structure.
