Abstract

The utility model discloses a high efficient and energy saving water heating furnace. A heating chamber is additionally arranged at the periphery of an internal furnace, a heat pipe is arranged on the upper part of a furnace body, a water hydrogen and oxygen separator is arranged at the lower part of the furnace body, and the arrangements that heating water pipes are vertically arranged, etc. are adopted. The heating area of the furnace body can be enlarged, the combustion condition of the utility model can be improved, and the furnace thermal efficiency can be enhanced.

Description

A kind of energy-efficient hot water space heating boiler

The utility model belongs to water circulation heating boiler.

At present, the hot water space heating boiler kind is a lot, adopted the measure of the multiple raising thermal efficiency and smoke abatement and dust control, as adopt the heat pipe conduction technique, second-time burning smoke and dust eliminating technology etc., but these measures are to adopt single technology mostly, and using method and installation position have nothing in common with each other, also influential mutually between measures, influence the burning of main furnace chamber and flue heat energy utilization as secondary combustion chamber to furnace flame.In addition, be subjected to the easy dust stratification dust fall of horizontal discharging of hot-water line in the general middle-size and small-size vertical boiler flue, influence the thermal efficiency of boiler.

The purpose of this utility model provides that a kind of heating surface area is big, pyroconductivity is high, the boiler combustion state is good, ature of coal is required the New-type boiler low, that smoke medicining dust-removing effect is good.

The technical solution of the utility model is: boiler furnace is made up of shell, flue, burner hearth etc., and the flue outer race has temperature-increasing box at the body of heater middle part, and the temperature-increasing box inner storing water communicates with the flue inner storing water.The temperature-increasing box flue communicates with burner hearth by the mouth that advances on the flue, and chimney breast is opened the opposite at the enterprising mouth of temperature-increasing box.All be provided with the many vertically disposed hot-water lines that are subjected in temperature-increasing box and the flue.Between the flue of upper of furnace body and burner hearth, be provided with heat pipe, abut against below the delivery port.Water hydrogen-oxygen separator is established in the body of heater bottom, and gas conduit leads under the fire grate.

The utility model has the advantages that: 1, body of heater middle part furnace gall periphery is added with temperature-increasing box, has increased the recirculated water heating surface area, has improved the heat energy utilization rate.2, heat pipe is located at upper of furnace body near delivery port, and leaving water temperature is raise, and has improved boiler thermal output.3, the body of heater bottom is provided with water hydrogen-oxygen separator, can combustion-supporting and smoke abatement and dust control, improved flame combustion state in the burner hearth, and boiler also can fully be burnt to colm.4, all of flue and temperature-increasing box all vertically are provided with by hot-water line, make to be subjected to that laying dust significantly reduces on the hot-water line, need not often to clean burner hearth, have not only improved the thermal efficiency but also alleviated labour intensity.

Accompanying drawing 1 is energy-efficient hot water space heating boiler side generalized section.

Accompanying drawing 2 is energy-efficient hot water space heating boiler normal cross-section schematic diagram.

Accompanying drawing 3 is an energy-efficient hot water space heating boiler middle part schematic cross section.

Be example with the vertical boiler in conjunction with the accompanying drawings, be described in detail as follows:

Boiler partly is made up of furnace shell 1, flue 2, burner hearth 3, temperature-increasing box 4, heat pipe 5 and water hydrogen-oxygen separator 6 etc.

Delivery port 7 is located at the top of flue 2, and water inlet 8 and water return outlet 9 are located at the bottom of flue 2.Temperature-increasing box 4 is located at the periphery of body of heater middle part flue 2, highly be about 1/3 of flue height, temperature-increasing box 4 inner storing waters communicate with flue 2 inner storing waters, have into mouth 10 on the one wing furnace courage of temperature-increasing box 4 and flue 2 overlappings, opposite side relative with advancing mouth 10 on the temperature-increasing box 4 is provided with chimney breast 11, burner hearth 3 interior flames are discharged behind two sideway swivel half cycles in temperature-increasing box 4 flues by advancing mouth 10 again, and flame swept away and was subjected to hot-water line 12 and tank wall in the temperature-increasing box 4, made heating surface area increase nearly 30%.All be provided with many in flue and the temperature-increasing box and be subjected to hot-water line 12, respectively be subjected to hot-water line to be vertical array, neither influence the burner hearth burning, reduced the charcoal ash deposition again.

Heat pipe 5 is located at upper of furnace body, and burner hearth 3 heats are directly delivered in the flue 2 below the delivery ports 7, to improve the boiler leaving water temperature.

Water hydrogen-oxygen separator 6 (patented technology) is located at burner hearth 3 bottoms, and the gas of generation leads under the fire grate, can combustion-supporting and smoke abatement and dust control.

Claims

1, a kind of energy-efficient heating boiler, form by furnace shell, flue, burner hearth, heat pipe, water hydrogen-oxygen separator etc., it is characterized in that: the flue outer race has temperature-increasing box at the body of heater middle part, the temperature-increasing box inner storing water communicates with the flue inner storing water, the temperature-increasing box flue communicates with burner hearth by the mouth that advances on the flue, chimney breast is opened the opposite at the enterprising mouth of temperature-increasing box, the hot-water line that is subjected in temperature-increasing box and the flue is vertical array, heat pipe is located between upper of furnace body flue and burner hearth, and water hydrogen-oxygen separator is located at the body of heater bottom.
