Abstract

The utility model discloses an environment-protecting energy-saving stream boiler which has a newly structural and external design and uses a water-fire pipe composite structure. A fireproof boiler wall is arranged in a boiler chamber so as to enhance the temperature of the boiler chamber and increase the insulating coefficient, the upper part of the boiler chamber is provided with water pipes which are obliquely installed, and the water pipes fully absorb radiation, generate convection to exchange heat and reduce smoke discharging temperature. The utility model is characterized in that a boiler liner is sheathed in a lower boiler shell, the upper part of the boiler liner is provided with a plurality of transverse water pipes which transversely penetrate through the boiler liner, are communicated with a water storing cavity and are obliquely installed, an ear-shaped box of one side of an upper boiler shell of the boiler body is communicated with a smoke-fire pipe, a plurality of ear-shaped water pipes are arranged in the box in parallel, the other side of the boiler body is provided with an ear-shaped smoke box, and the smoke box and the ear-shaped box of the corresponding side are provided with a plurality of smoke pipes transversely penetrating through the water storing cavity of the upper boiler shell.

Description

Environmental protection and energy saving swallow boiler furnace

The utility model is a kind of steam boiler, a kind of specifically fuel-firing gas-firing steam boiler of extreme misery pipe combined running.

Increasingly serious along with energy conservation and environmental protection, oil-burning gas-fired boiler substitutes the combustion raw coal boiler has become inevitable trend.At present, the more domestic oil-burning gas-fired boiler that moulding have been arranged, wherein vertical steam boiler mostly is the unfired tube formula, combustor sprays into fuel from top, in the burner hearth internal combustion that surrounds by the solid matter water pipe, after secondary cycle by cigarette by discharge.This kind type of furnace is for guaranteeing that degree of supercooling is suitable in the burner hearth, and furnace diameter has been strengthened in the bigger combustion space of essential reservation when doing like this.Its whole heat convection faces are parallel baffled, and the heat exchange effect is good not as transversal flow.And burner hearth inner ring pipe thermal deviation is more obvious.

The utility model purpose is to disclose a kind of environmental protection and energy saving steam boiler.Adopt extreme misery pipe composite construction.Fire-resistant furnace wall improves fire box temperature, increases to protect hot coefficient.The water pipe that install at the inclination angle fully absorbs radiation, and heat convection reduces exhaust gas temperature.Two backhaul smoke pipes can improve flue gas flow rate, reduce dust stratification, strengthen heat exchange.

The utility model is by the pot body, flue, and refractory burner hearth, water pipe, flue and temperature, manometer is formed, and it is characterized in that:

＜A 〉. the pot body by upper cover 6, upper boiler cover 7, down shell 18, undergauge end socket 13 is formed between the shell up and down;

＜B 〉. flue is to be sleeved on down in the shell 18, is made up of flue tube 15, flue top 12, pyrotechnics pipe 11; Lower bottom part is to build the refractory burner hearth 19 that flame retardant coating 16 is arranged in the flue, and refractory burner hearth corresponding height place has combustor interface 17;

＜C 〉. the U type leftover bits and pieces 20 that is connected with flue by described inner surface of pot body and flue outer surface and pot body bottom forms the water storage cavity of boiler, has one group on the top of flue by the many horizontal water tubes 14 that cross the inclination installation that communicates with water storage cavity in flue;

＜D 〉. pot body upper boiler cover 7 one sides have an ear molding box, and the ear molding box communicates with pyrotechnics pipe 11, and there is a dividing plate centre, top and bottom and side arrangement many ear type water pipes 1 arranged side by side in its case, ear type water pipe 1 communicates with the water storage cavity of upper boiler cover;

＜E 〉. pot body upper boiler cover opposite side has an ear type smoke box 9, and smoke box 9 is respectively arranged the many smoke pipes 10 that pass across the water storage cavity of upper boiler cover with the space up and down of the corresponding molding box dividing plate of picking up the ears, and two groups of smoke pipes 10 form the V-arrangement flue up and down;

Fig. 1 is the utility model embodiment master cutaway view.

Fig. 2 is the A-A cutaway view of Fig. 1.

2 is that a pair porthole, 3 is that main inlet throttle-stop valve, 4 is that steam-water separator, 5 is that safety valve, 25 is that hand hole workpiece, 27 is the pressure gauge stand, is installed in a pot body upper cover place among the figure; 8 for explosion proof door, be positioned at smoke box (9) upper surface; 28 is that temperature gauge stand, 29 is the water level meter, is installed on upper boiler cover 7; 26 for chimney, down on the shell hand hole workpiece 25, feedwater base 24, visor 30 are being housed, stove seat pad plate 21, blow-off pipe 22, ring-like dirt sucking tube 23 are equipped with in its shell bottom.

The utlity model has brand-new structure and exterior design, adopt extreme misery pipe composite construction.Arrange fire-resistant furnace wall in the burner hearth, improve fire box temperature, increase and protect hot coefficient.Upper furnace is arranged the water pipe that install at the inclination angle, fully absorbs radiation, and heat convection reduces exhaust gas temperature.Upper of furnace body is arranged the two backhaul smoke pipes that install at the inclination angle, because caliber relatively more carefully can improve flue gas flow rate, reduces dust stratification, strengthens heat exchange.Arrange the ear type water pipe that straight flange tilts in the smoke box, prevent the corner build-up of limescale.The welding fin reduces refractory material and body of heater weight between syrinx, has reduced cost, has improved the burner hearth air-tightness.

The environmental protection aspect, for reaction SO2+O2-SO3, if there is not excess air (O2) just can not take place, so this boiler series all selects advanced import combustor for use, and adopts and monitor accordingly and automatic control technology.Guaranteeing to make excess air coefficient less than 1.03 under the strict air-tightness prerequisite, reduce exhaust gas volumn and improved boiler efficiency.Satisfy the condition of low oxygen combustion simultaneously, also reduced the generation of V2O5 and NOX.

Boiler uptake can be opened at any time and check cleaning.The water pipe section is provided with hand hole or maintenance and inspection removing incrustation scale is convenient in a hole.

Because domestic many producers introduce external designing technique, so some welding procedure does not meet in China " steam boiler safety and technical supervision rules " (1996) the 48th regulation, and this boiler design is calculated manufacturing process etc. and is all carried out in strict accordance with " rules " regulation, except that the weld seam of smoke pipe and horizontal water tube is that other is butt weld the fillet welding.The simple relatively weld seam of whole manufacturing process is convenient to processing and is detected mostly outside.

The utility model is compared with the same model boiler, and overall dimensions obviously reduce a lot.Economical with materials reduces cost.
