Abstract

An integrated condensation steam boiler belongs to the field of heating equipment, and relates to a fuel and gas wet back two-return-trace pot shell type hot water or steam boiler. The technical scheme is that the integrated condensation steam boiler utilizes a horizontal two-return-trace structure and comprises a hearth, a boiler barrel, a reversal chamber, an economizer and a condenser, wherein the reversal chamber is arranged at the right portion of the hearth, and a spring type safe explosion door is arranged at the right portion of the reversal chamber. The reversal chamber is connected to a smoke inlet of the economizer arranged in a front smoke box at the left upper portion of the hearth through180-degree rotation of a convection tube bundle, and a smoke outlet of the economizer is connected with a smoke inlet of the condenser. The integrated condensation steam boiler has the advantages that the hearth, a convection heating surface, the economizer and the condenser of the boiler can utilize waste heat of smoke in a cascade mode according to grade of heat energy, thereby fully improving efficiency of the boiler. The heating surface of the condenser is formed by steel aluminum composite fin pipes, thereby having good heat conduction performance. The condenser heats water in a softened water tank in a circulation mode, thereby lowering temperature of exhausted smoke, removing part of oxygen contained in water in a water tank and prolonging service life of the boiler.

Description

A kind of integral type condensed steam boiler

Technical field

The utility model belongs to the heating equipment field, relates to the wet back of the body two backhaul pan shell type hot water or the steam boilers of a kind of fuel oil, combustion gas.

Background technology

In recent years, because the fuel vapor boiler volume is little, automaticity is high, and is easy for installation, obtained using widely.With the natural gas is the boiler of fuel, and discharged flue gas has quite high temperature, is about 150~250 ℃, and it contains about 15%~19% (the volume composition) of steam, is the main carrier of flue gas heat.If the exhaust gas temperature of boiler is dropped to enough low level, the steam that is superheat state so in the flue gas will condense and emit the latent heat of vaporization, and the boiler that makes the latent heat of vaporization in the flue gas be able to recycle is called condenser boiler.

Can know that according to the steam partial pressure coefficient water dew point is generally at 56~60 ℃ in the flue gas.We reclaim the sensible heat and the latent heat of flue gas simultaneously through reducing flue-gas temperature to dew point with refrigerant medium (like cold water, cold air etc.).Another effect of flue gas condensing is the discharging that reduces NOx.Its reason is the raising of the condenser boiler thermal efficiency on the one hand, has reduced the consumption of fuel, has reduced total release, and condensate liquid has further reduced discharging again to the absorption of NOx on the other hand, and boiler thermal output is further improved.About 10.3 NM3 of 1NM3 natural gas burning production theory exhaust gas volumn (approximately 12.5KG).With excess air coefficient 1.3 is example, produces flue gas 14 NM3 (approximately 16.6KG).Get flue-gas temperature and be reduced to 70 ℃ for 200 ℃, emit the about 1600KJ of physics sensible heat, the water vapor condensation rate gets 50%, emits about 1850 KJ of the latent heat of vaporization, amounts to heat release 3450 KJ, is 10% of natural gas low heat valve approximately.Get into heat-energy recovering apparatus if get 80% flue gas, can improve the heat energy utilization rate more than 8%, save gas fuel nearly 10%.

Summary of the invention

The purpose of the utility model is the characteristics and not enough a kind of thermal efficiency of design integral type condensed steam higher, energy-conserving and environment-protective more boiler to existing condensing steam boiler.

The technical scheme of the utility model is: this device adopts horizontal two return structures, is made up of burner hearth, stove tube, the chamber of strile-bacing, energy-saving appliance and condenser, and wherein burner hearth adopts corrugated flue; The burner hearth right part is established the chamber of strile-bacing; The chamber right part that strile-backs is equipped with the spring type safety explosion proof door, and the chamber of strile-bacing is connected to the gas approach that is located at energy-saving appliance in the burner hearth upper left quarter front smoke box for 180 ° through the convection bank revolution, and the exhanst gas outlet of energy-saving appliance links to each other with the condenser gas approach; The finned tube outlet of energy-saving appliance links to each other with boiler stove tube; The import of energy-saving appliance finned tube links to each other with softened water tank, and the finned tube two ends of condenser externally all link to each other with softened water tank, are internally connected with aqua storage tank at condenser; Convection bank is a threaded flue; The condenser fin pipe is a steel-aluminum composite fin tube, is covered with the enamel anticorrosion layer in the condenser shell; Boiler stove tube top is equipped with utmost point low water level protective device.

The beneficial effect of the utility model: the burner hearth of boiler, convection heating surface, energy-saving appliance, condenser fully improve boiler efficiency according to grade, the fume afterheat cascade utilization of heat energy; The heating surface of condenser is made up of steel-aluminum composite fin tube, and heat conductivility is better; Condenser has not only reduced exhaust gas temperature to the heating that circulates of the water in the softened water tank, has also got rid of the part oxygen of water in the water tank simultaneously, has improved boiler life.

The specific embodiment

The burner hearth 1 of this device adopts corrugated flue, and burner hearth 1 right part is provided with the chamber 2 of strile-bacing, and chamber 2 right parts that strile-back are equipped with spring type safety explosion proof door 3.The chamber 2 of strile-bacing is connected to the gas approach 5-4 that is located at energy-saving appliance 5 in the burner hearth 1 upper left quarter front smoke box for 180 ° through convection bank 4 revolution, and the exhanst gas outlet 5-5 of energy-saving appliance 5 links to each other with condenser gas approach 7-5, and flue gas is discharged from condenser exhanst gas outlet 7-6 at last.The finned tube outlet 5-3 of energy-saving appliance 5 links to each other with boiler stove tube 6, and energy-saving appliance finned tube import 5-2 links to each other with softened water tank.The finned tube 5-1 of energy-saving appliance 5 is that stagger arrangement arranges that high-frequency welding processes.

The finned tube 7-1 two ends of condenser 7 externally all link to each other with softened water tank, are internally connected with aqua storage tank 7-4 at condenser 7; Condenser 7 finned tubes adopt ND steel (09CrCuSb) steel-aluminum composite fin tube to make its acid corrosion-resistant performance, anti-chlorine ion corrosion function admirable.Because the heating surface of condenser 7 mainly is made up of steel-aluminum composite fin tube, and the heat conductivility of aluminium is better, corrosion resistance is weaker than stainless steel, is better than copper, and adapting to fully with the natural gas is the boiler of fuel; The finned tube import 7-3 of condenser 7 links to each other with softened water tank, and other end outlet also links to each other with softened water tank, to the heating that circulates of the water in the softened water tank, has not only reduced exhaust gas temperature, and the part oxygen that the while has also been got rid of the interior water of water tank has improved boiler life; The finned tube 7-1 of condenser 7 is that stagger arrangement is arranged, is covered with the enamel anticorrosion layer in condenser 7 housings.

Convection bank 4 is a threaded flue.Boiler stove tube 6 tops are equipped with utmost point low water level protective device 9, directly detect drum 6 water level inside, reduce the probability of wrong report, improve safe operation of the boiler.
