Abstract
The utility model relates to an atmospheric hot-water boiler, which is characterized in that a middle arch and a side arch are arranged in a boiler chamber, a gas combustion chamber is formed between the middle arch and the side arch, and combustible gas generated by fuel in the process of combusting can be sufficiently combusted in the gas combustion chamber. The utility model has the advantages of high heat efficiency, pollution prevention and energy saving, can furthest convert the combustible component of coal to heat energy, and is particularly suitable for combusting briquette.
Description
The utility model is a kind of normal-pressure hot-water boiler, is particularly suitable for briquet.
Press national regulation, at SO
2In the control zone, the diffusing coal of forbidding to burn will be promoted the use of electricity, oil, gas and clean fuels such as moulded coal, coal washing.Existing coal-burning boiler mostly is unsuitable for briquet, and it is insufficient to burn in the use, and result of use is poor.
The purpose of this utility model be the design a kind of can briquet and the good hot-water boiler of result of use.
The utility model comprises body of heater, is provided with burner hearth in it, and the top of burner hearth is connected with chimney, and the bottom is provided with fire grate and combustion chamber, and convection tube is installed in the burner hearth; Body of heater is provided with the coal feeding hole that is communicated with burner hearth, and the bottom of body of heater is provided with air inlet, it is characterized in that being provided with in the burner hearth hogging and limit arch, forms gas combustion chamber between hogging and the limit arch.
Body of heater of the present utility model is provided with the secondary air mouth that is communicated with burner hearth at the position corresponding to gas combustion chamber.
The utility model is owing to be provided with hogging and the limit arch in burner hearth, in use, initiate coal is through after preheating, destructive distillation, volatilizing, catch fire, and the fuel gas that is produced flame when burning is anti-from the hogging both sides, because the effect of limit arch makes both sides flame in the indoor mixing of gas combustion.Owing to form negative pressure in the draft of chimney, burner hearth, replenish air by the second-time burning air inlet, make fuel gas form second-time burning, effectively raise the thermal efficiency of boiler.The utility model can make the flammable composition of coal be converted to heat energy to greatest extent, reached not only to prevent to pollute but also the purpose of energy savings, particularly is suitable for being used for briquet.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the external form front view of the utility model embodiment;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the structural representation of hogging;
Fig. 4 is the structural representation of limit arch.
