Description

Efficient non-pressure heating hot water two purpose boiler

The utility model relates to a kind of heating boiler, particularly is suitable for the miniature boiler of family's heating hot water dual-purpose.

At present, common civilian middle-size and small-size heating boiler mostly is the vertical or cube formula of drum, and its structure is sleeved flue.In use have following shortcoming and defect: 1. unreasonable because of Combustion chamber design, effective area is little, and heat-energy losses is bigger; 2. fuel uses the kind strictness, makes single-fuel with coal or kerosene, honeycomb briquette etc., can not or other fuel of dual-purpose preferably; 3. the grey scab of flue surface prolong knot because the restriction of structure, can't be removed and influences the thermal efficiency; 4. inconvenience maintenance, general boiler bladder is if damaged drainage occurs, and then whole stove is promptly accused and is scrapped; 5. existing boiler bottom gate is the stationary structure that can not open, difficulty and the influence burning of rock spoil removal class bulk slag, and dust flies upward contaminated environment during scarfing cinder; 6. the structure thermal circulation performance is poor, is being used for heating, owing to be subjected to the restriction of radiator and boiler room absolute altitude, often needs boiler erection in darker cellar.

The purpose of this utility model provides a kind of boiler that is specially adapted to heating of cold district household small-size and heat supply water dual-purpose, and it can overcome the above-mentioned shortcoming and defect that middle-size and small-size heating boiler commonly used at present exists effectively.

Major parts such as the combustion chamber that the utility model is surrounded by top combination flue and lower support framework and tile stove wall, grate, fire door are formed.Flue is to be combined by board-like M type water jacket that is arranged in parallel up and down and L type water jacket, last lower water jacket is communicated with by a tube connector, the U type space that M type water jacket madial wall is surrounded is the horizontal gyrating type flue of boiler, L type water jacket has the flame gas passage of 1/2 water jacket width in a side that is positioned at the stove rear end, communicate with a side of the horizontal rotation flue of boiler, be positioned at the stove rear end and set out water pipe corresponding to flame gas passage place on M type water jacket, the downside that is positioned at the stove rear end at L type water jacket is provided with return pipe.Flue below is the combustion chamber that is cuboid, also is equipped with before the furnace chamber that places the grate front end dull and stereotypedly and place the treadmill of grate rear end on the grate underframe, and treadmill moves forward and backward it by connected operating grip.

Be provided with flue dust and dirt cleaning door at the stokehold end.

Horizontal cuboid design of the present utility model has the cuboid combustion chamber of growing up, all kinds of solid fuels that can disposable a large amount of adding Any shape.During work, can treat the afterburnt with lime-ash or red-hot sinter horizontal sliding to treadmill, take out out treadmill, lime-ash falls into grey thorax, and it is light clean again making prepurging work.Another purposes of treadmill is can twitch to open a suitable slit and make air directly enter rear combustion chamber, mixes the good second-time burning of generation near flame gas passage with fuel gas.Can preset a certain amount of fuel on the flat board before the furnace chamber, when the need continuous heat supply, can allow the fuel of full furnace chamber burn from treadmill, dull and stereotyped to the fire door place before furnace chamber, burned flame directly acts on flue always, and enter the swinging flue by flame gas passage, heated water (flow) direction and flue gas flow direction basically identical, delivery port are in the most concentrated flame gas passage place of flame, have increased the heating surface area of aqueous medium, prolonged heated time, the heat energy utilization rate is improved.Because of boiler has less free height, easy to install, system's thermal cycle speed is fast.Because its horizontal gyrating type flue does not have any dead angle, can extremely make things convenient for, remove effectively dust and dirt in the flue by the dust and dirt cleaning door.Therefore, the utlity model has energy-efficient, clean dustless, the advantage of being convenient to the installation, maintenance maintenance, and strong, can burn coal, firewood, can burn grass, sawdust, stalk etc. again the adaptability of fuel.Heating, heat supply water dual-purpose, cheap for manufacturing cost, manufacture craft is good.

Below with regard to accompanying drawing embodiment of the present utility model is described in further detail.
