Description
Technical field
The utility model relates to a kind of energy saver of coal furnace, particularly participates in decomposing and the energy saver that burns by water.
Background technology
Present coal furnace divides large scale industry boiler and small-sized domestic burners two classes, and Industrial Boiler divides the pressure boiler that utilizes steam again and utilizes the pressure-less boiler two big classes of hot water, but they all do not have the function of metabolic water.Sometimes in order to improve burning velocity and furnace temperature, the practice commonly used is additional blowers or increases chimney, but this can increase power consumption again or limit by condition be difficult to chimney add very high.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and participates in decomposing and the energy saver that burns by water and provide a kind of, to reach the purpose that reduces discharging, energy savings.
The technical solution of the utility model is, this kind is used for the combustion water energy saver of coal furnace, comprise burner hearth, be positioned at the fire grate or the fire grate of burner hearth below, it is characterized in that, in burner hearth or sidewall be provided with the cavity type vapourizing unit, an end of this vapourizing unit is connected with the water of by-pass valve control/steam pipe road, the other end connects steam lead, and steam lead connects the jet pipe of fire grate or fire grate below band puff prot.
For the normal domestic coal dust ball stove, described vapourizing unit is the coil pipe of coiled coil on hearth wall, and this coil pipe one end is connected with the water lines of by-pass valve control.
For the industrial hot water boiler, described vapourizing unit is watt shape vapourizing unit that is arranged on the burner hearth sidewall, and this watt shape vapourizing unit one end is connected with the water/steam pipe road of by-pass valve control.
Scatter and disappear for reducing heat, improve the vapor (steam) temperature at spout place, for the normal domestic coal dust ball stove, jet pipe external application heat-insulation layer, heat-insulation layer is provided with the gas port consistent with puff prot.
For the industrial hot water boiler, except that taking above-mentioned insulation measure, between watt shape vapourizing unit and burner hearth, be provided with insulation material.
The utility model provides a kind of energy-conservation device of water that fires, by water/steam pipe road, by-pass valve control, vapourizing unit and be loaded on fire grate or fire grate under puff prot form.Can connect water supply installation by water/steam pipe road, by water generates steam.Can save this device for the steam pressure boiler, directly connect steam pipework.Operation principle is as follows: water supply installation provides pure water source, is installed in the position more taller than the upper end of stove, and purpose provides the water source of certain pressure, and valve is used for controlling flow makes the high-temperature water vapor amount of puff prot ejection just right.The effect of vapourizing unit is fraction heat (industrial furnace) or the waste heat (domestic burners) that utilizes stove to produce, the water that water supply installation is provided is heated as high-temperature steam, the pipe that leads to fire grate or fire grate below is equipped with on vapourizing unit top, its objective is and guide high-temperature steam into the stove below, and by upwards ejection of connected air jet system (one group of puff prot), cooling-down effect when not having air blast fully can only make flame more prosperous.When passing through in the stove owing to the elevated temperature heat dry saturated steam again, generate flammable and combustion-supporting gases such as hydrogen, oxygen, carbon monoxide, methane, ethane with coal reaction red-hot in the stove, these gases can be given birth to heat in reaction in furnace again, and institute is so that increase in temperature in the stove, and increasing of temperature makes burning fully.
Thereby the beneficial effects of the utility model are, have energy-conservation and reduce the dual good result of exhaust pollution, and after the test at low-pressure boiler showed, uses this device, fire door flame increased nearly one times, more than increase in temperature 300 is spent, and synthesis energy saving effect about 30%.This device meets the requirement that makes up economizing type harmonious society, popularizes in an all-round way, and to delaying global warming, the ecological balance of preserving our planet, of far-reaching significance.
