Abstract
The utility model relates to a briquette boiler, comprising a boiler body, a fire grate, a transverse water pipe and a chimney. The boiler body is the interlayer structure. The lower part of the boiler body is provided with the fire grate. The wall of the boiler body corresponding to the upper part of the fire grate is provided with a coal throwing opening, and the lower part of the boiler body is provided with an ash cleaning opening. The upper of the boiler body is provided with a chimney. The transverse water pipe is arranged in the boiler body. The center of the boiler body corresponding to the coal throwing opening is fixedly provided with an annular boiler hearth barrel. A partition plate is fixedly connected between the boiler body and the outer wall of the upper part of the boiler hearth barrel. The partition plate is provided with more than 1 smoke outlet. The utility model has the advantages of simple structure, convenient operation, complete coal-combustion, little energy consumption, environmental pollution reduction, fast temperature rising, and no scaling of the boiler.
Description
The utility model belongs to the domestic boiler class, specifically is a kind of molded coal boiler.
In the boiler of market sale now, mostly be that stove fire directly heats string water pipe and flue, thereby the mode that adds hot water is finished, this mode of heating has existed energy consumption big, the thermal efficiency is low, it is slow to heat up, easy fouling and the serious deficiency of environmental pollution, at this deficiency, people have done some improvement to the fire coal and the combustion system of boiler, changing single fire grate is double grate, diffusing coal changes moulded coal into, these improve all has than obvious effects improving environmental pollution energy-conservation reaching, and does not significantly improve but the commute fouling and the thermal efficiency are low, does not have pressure air feed multipurpose furnace as Chinese patent communique disclosed secondary inverse burning hot pipe on September 30th, 92, it is mainly by body of heater, burner hearth, the combustion chamber, valve, chimney, feed pipe, anti-riot safety device constitutes, on in body of heater, having established directly, following twice heat absorption fire grate and heat pipe, and be furnished with preheating water tank and no pressure-controlled valve, this stove is greatly improved the rising speed of water temperature, but still do not solve easy fouling, energy consumption is big, fired coal combustion is incomplete, pollutes bigger problem.
It is a kind of simple in structure that the purpose of this utility model is to provide, and boiler is less scaling, and fired coal combustion is complete, and energy consumption is little, reduces the molded coal boiler of environmental pollution.
The utility model is achieved through the following technical solutions:
It is molded coal boiler, comprise body of heater, fire grate, horizontal water tube and chimney, body of heater is a sandwich, and fire grate is installed in the bottom of body of heater, and the furnace body wall on corresponding fire grate top has coal feeding hole, the bottom has cleaning door, upper of furnace body is installed chimney, and horizontal water tube is installed between the body of heater, the relative coal feeding hole fixed installation annular furnace tube at the body of heater center, the dividing plate that is connected between the external wall of upper portion of burner hearth tube and the body of heater has 1 above outlet flue on dividing plate.
Described horizontal water tube is closed, the fin of the fixedly connected helical form fin in two ends or multi-disc wing fin or other shape.
Described burner hearth nozzle and coal feeding hole is isometrical or greater than the coal feeding hole diameter, and its underpart and fire grate leave a determining deviation.
Describe in further detail below in conjunction with accompanying drawing:
Fig. 1: the utility model structural representation.
Among the figure: 1 impact tube, 2 bodies of heater, 3 fin, 4 horizontal water tubes, 5 pipes, 6 coal-feeding doors, 7 burner hearth tubes, 8 moulded coals, 9 furnace chambers, 10 fire grates, 11 shoot doors
In use, earlier fill with water to boiler, give from coal-feeding door 6 again and add moulded coals 8 in the burner hearth tube 7 and light, during burning, control the just burning and anti-burning of moulded coal 8 by control coal-feeding door 6 and shoot door 11, so that moulded coal 8 burnings fully, as when needing moulded coal 8 to burn in the mode of just burning, close coal-feeding door 6, open shoot door 11, air is entered in the body of heater 2 from shoot door 11, thereby realize just burning, after just burning certain hour, close shoot door 11 again, open coal-feeding door 6, air is entered from coal-feeding door 6, realization is to the burning on moulded coal 8 tops, reach the purpose of anti-burning, make moulded coal 8 burnings fully, fully, the flue gas that burning generates is through the lower plane of burner hearth tube 7, and pass part moulded coal on the fire grate 10, because the gap between moulded coal is very little, so flow velocity is very high when passing, and because of the moulded coal placement that is staggered, therefore disturbance is very strong, then but burning fume evenly mixes with fresh air fully, makes moulded coal 8 fully obtain burning, and high-temperature flue gas is through pipe 5 then, enter furnace chamber 9 and wash away horizontal water tube 4, the temperature of the medium in the horizontal water tube 4 is raise gradually, and medium circulates in the horizontal water tube of sealing, and helical form or the flap-like fin 3 of the heat of medium by two ends is dispersed in the water in the flue that body of heater 2 constituted, water is heated once more, totally-enclosed because of horizontal water tube 4, so non flouling behaviours in the horizontal water tube 4, and helical form or flap-like fin 3 stretch with the difference of temperature when water temperature changes or crooked, make in the above the incrustation scale that forms along with flexible or crooked and come off automatically, at last, flue gas is discharged through impact tube 1, and the flue gas of discharge has been eliminated the existence of black smoke.
The utlity model has following advantage:
1, simple in structure, easy to use.
2, fired coal combustion is complete, and energy consumption is little, environmental contamination reduction.
3, quick heating, the boiler non-scaling.
