Description

A kind of desirable boiler

Affiliated technical field

The present invention relates to a kind ofly adopt the heating of airtight metal furnaces to be connected with its outer wall and form the steam in the interior mistake heat exchanger of steam room (pot), the stove of mezzanine space and produce a kind of desirable boiler of high-pressure and high-temperature steam, not only environmental protection especially can improve the new equipment of Energy Efficiency Ratio.

Background technology

At present, known various boilers, its body of heater generally is comprised of combustion apparatus, burner hearth, flue etc., is characterized in that the outlet of flue gas communicates with atmosphere, i.e. and the stove of non-seal is so the raising of the Energy Efficiency Ratio of plain cylindrical furnace is greatly limited.Not long ago, I have proposed to adopt the technical scheme of airtight metal furnaces, be not connected with the interior overheated heat transmission equipment of putting of body of heater but have to adopt the vapor transfer pipeline to pass the furnace wall steam room (pot) outside this furnace wall, so do not satisfy the needs of some needs high-pressure and high-temperature steam.

Summary of the invention

Because communicating with atmosphere, exhanst gas outlet cause the raising of Energy Efficiency Ratio to be restricted in order to break through conventional oven, especially can satisfy the needs that produce high-pressure and high-temperature steam, the invention provides a kind of airtight metal furnaces of utilizing furnace sealing to produce larger pressure and higher temperature, the heating steam in the steam room (pot) that forms water interlayer that is connected with its furnace wall not only, and placed the steam of the overheated heat transmission equipment of furnace chamber by the flame in the body of heater and flue gas, and then realization produces the steam of larger pressure, higher temperature, not only energy-conservation, and improve purposes.

The technical solution adopted for the present invention to solve the technical problems is: form the airtight metal furnaces that an inside connects each other by combustion apparatus, burner hearth, smoke chamber, be equipped with flue gas pressure limiting valve, flue gas safety valve, flue gas pressures controller or temperature controller, flue gas pressures table and flue-gas temperature meter on the airtight metal furnaces, the flue dust storage tank that the smoke discharging mouth of pipe of flue gas pressure limiting valve and flue gas safety valve is put in addition through condensation pipe and body of heater links, be equipped with dirt gas on the flue dust storage tank from device, the outlet of the gas of dirt gas separating device communicates with atmosphere.Be provided with flue gas or flame check-valves and be equipped with the forced fan that is connected with gas import department in the gas import department of metal furnaces.In addition, metal furnaces is built-in with fire grate or soot particle filter and dust collection chamber, and the bottom of stove is equipped with the aperture of door for maintenance, ash disposal.

Connect and form the metal steam room (pot) of mezzanine space outside the metal furnace wall, the furnace wall that steam room (pot) connects is the steam heating surface, steam in the steam room (pot), be equipped with Pressure gauge, thermometer, tank gage, safety valve and pressure controller or temperature controller on the pot, the outer wall of pot is equipped with thermal insulating warm-keeping layer.

The metal furnace chamber was built-in with heat exchanger, what cross heat exchanger is flame or flue gas on every side, the steam that the steam input mouth of pipe of crossing heat exchanger passes the steam room (pot) outside furnace wall and the furnace wall is exported the mouth of pipe and is connected, cross in the heat exchanger is steam, the steam output pipe mouth of crossing heat exchanger passes the furnace wall outward supplying heat, is equipped with safety and control device at steam outlet.

If process waste vapour, desulfurization etc., can before the flue dust storage tank, install treating apparatus; If the useless cigarette waste heat of utilization can arrange water jacket at condenser pipe, and with in the hot water input pot, certainly, also UTILIZATION OF VESIDUAL HEAT IN directly can be supplied with the place that other use heat.

The invention has the beneficial effects as follows, owing to utilize furnace sealing, under the condition that pressure control and safety devices are arranged, the metal inner flue gas of the stove can reach higher temperature because obtaining heating, pressure increases, connect the steam room (pot) outside the furnace wall and place the steam of the overheated heat transmission equipment in the furnace chamber just can obtain more heat, not only can significantly improve the Energy Efficiency Ratio of boiler, and can produce the water vapour of high pressure-temperature.

The specific embodiment

Airtight metal furnaces is by combustion apparatus (containing the burning input unit), burner hearth (combustion chamber), smoke chamber UNICOM consists of, the air inlet place that burner hearth (combustion chamber) is located is provided with flue gas or flame check-valves and forced fan, the gas delivery outlet of forced fan is connected with the gas import of metal furnaces and communicates with the metal furnaces inner chamber, burner hearth is built-in with fire grate or cinder grain filter, configuration flue gas safety valve on the metal furnaces, the flue gas pressure limiting valve, flue gas pressures controller or flue-gas temperature controller, the flue-gas temperature meter, the flue gas pressures table, be equipped with the soot particle filter before the smoke inlet of flue gas safety valve and pressure limiting valve, the mouth of pipe of the drainage flue gas of flue gas safety valve and pressure limiting valve is through condensation pipe and place the flue dust storage tank outside the stove to link, configuration dirt gas separating device on the flue dust storage tank, the gas outlet of dirt gas separating device communicates with atmosphere, and the bottom of flue dust storage tank is provided with the ash discharge aperture of door.
