Technical field
The utility model belongs to boiler technology field, is specifically related to a kind of power economized boiler.
Background technology
Boiler be civilian or industrial in heating, heat indispensable equipment, traditional boiler, only by boiler inner wall is directly heated the water in interlayer is heated, and fuel adopts coal, gas, wet goods fossil energy conventionally, along with non-renewable fossil energy sharply reduces, it supplies growing tension, and fuel price also rises steadily simultaneously.The defect that adopts in addition above-mentioned fuel to have high pollution and waste energy.Biomass fuel is as a kind of renewable resource alternative energy source, to improving environment, reduce C02 content in atmosphere, reducing " greenhouse effects " has great benefit, is utilized just gradually, and China is as a large agricultural country, biomass resource is very abundant, and according to statistics, the annual biomass energy of producing of China is about 700,000,000 tons, and traditional processing method not only causes poor efficiency utilization and the waste of biomass resource, also pollute environment simultaneously.And a main channel using burner as biomass resource utilization is recognized by people just gradually, existing burner ubiquity fuel in combustion chamber easily pile up, burn insufficient, easy coking, undesirable, the easy tempering of burn-off rate, product fluctuation of service, have the problems such as certain danger.
Boiler is mostly monomer structure at present, water is stored in the exocoel of combustion chamber stove, exhaust steam passage is shorter, holdup time is shorter, cause a large amount of heats to fail to make full use of, just discharge through exhaust opening, well do not utilize the thermal energy in waste gas, cause a lot of thermal energy wastes in waste gas, make the intensification of water in stove slower, a large amount of heat energy goes out of use and dust is taken away, waste the energy, and because the waste gas after the fuel combustions such as fire coal and dust directly enter in atmosphere by external chimney, pollute greatly environment, wasted resource.In the today of advocating energy-saving and emission-reduction, people have carried out various transformations to boiler, but all have the problems such as fuel can not fully burn, and heat energy can not make full use of, and air pollution is serious.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of Multiple Cycle heat absorption energy-saving boiler.
A kind of Multiple Cycle heat absorption energy-saving boiler, from the bottom to top by base, base, fire grate, furnace shell composition, in described furnace shell, be provided with combustion chamber, flue, one journey is returned smoke pipe, two journeys return smoke pipe and three journeys are returned smoke pipe, a described journey is returned smoke pipe and is connected with flue and combustion chamber, two journeys are returned smoke pipe, three journeys are returned smoke pipe and are passed through respectively upper spacer, lower clapboard is connected with flue and combustion chamber, combustion chamber is provided with ash discharging hole, ash discharging hole and charging aperture, base is provided with slag-drip opening, in combustion chamber, be provided with filter course, fire grate, in described combustion chamber, be provided with undaform furnace grate tube, increase coal storage and heat exchange area, it is outer around heat exchange coil that a described journey is returned smoke pipe, described heat exchanger tube is divided into heat exchange coil from the bottom to top, U-shaped heat exchanger tube and secondary heat exchange coil pipe, boiler top is provided with secondary heat exchanger, and described secondary heat exchange coil pipe is located in secondary heat exchanger, secondary heat exchange coil pipe, heat exchange coil, U-shaped heat exchanger tube is integrated, described U-shaped heat exchanger tube is distributed in heat exchange coil around, and bottom air inlet is provided with air blast, and top is gas outlet, described heat exchange coil inwall is evenly distributed with conducting strip, owing to being provided with conducting strip in heat exchanger tube, has accelerated heat transfer effect.
The utility model in use, is knocked down undaform furnace grate tube by fuel from charging aperture, after igniting, the anti-burning of flame presses down, and returns smoke pipe enter a journey and return smoke pipe by a journey, enters three journeys return smoke pipe by filter course overhead, enter again smoke-box, discharged to secondary heat exchanger, then by chimney combustion gas.When water in stove or medium are raised to after uniform temperature, open air blast by force by the heat circulation in heat exchange dish, enter secondary heat exchange coil pipe, further by UTILIZATION OF VESIDUAL HEAT IN, thereby reach the object of energy-saving heating.
