Description

Condensing Hot water units
Technical field
The utility model relates to a kind of condensing Hot water units.The fuel of this condensing Hot water units, adopt combustion gas class clean fuel, boiler heating chamber adopts finned tube heat exchange structure.The pipe heat exchanger of original boiler is replaced, in order to improve the condensation of water at low temperature to water vapour in flue gas with finned tube exchanger.Owing to being provided with finned tube exchanger in the unit, greatly can improve the thermal efficiency of unit, reduce the weight and volume of unit.Condensing Hot water units mainly produces normal pressure, normal temperature hot water, for heating, the life and industrial manufacture process hot water etc. of building.
Background technology
At present, traditional gas normal-pressure hot-water boiler is all made up of burner, combustion chamber, heating clamber three major part.Ignited fuel is mainly provided enough air by burner, and combustion chamber is heat by the fuel after lighting and air at this burning conversion, and heating clamber is the heat of high temperature will produced in combustion chambers burn process, pass to water at low temperature and the temperature of water is improved.The efficiency of boiler depends primarily on structure and the heating surface area of heating clamber, the heating clamber of existing boiler adopts tubular type heating arrangement mostly, because the heat transfer coefficient of tubular type heating arrangement is low, high fume temperature does not have water vapour condensation in flue gas, so boiler efficiency is very low.This condensing atmospheric hot-water unit changes the heated structure of heating clamber, change original tubular type heating arrangement into finned tube heat exchange structure, the heat transfer coefficient of finned tube heat exchange is very high, well can carry out condensation to water vapour in flue gas, reclaims the latent heat of a large amount of water vapour in flue gas.Often burn cubic metre of imflammable gas in the unit, and approximately will produce 1 ~ 2 kg of water, at high temperature water is heated, the latent heat that per kilogram water approximately will absorb 560 kilocalories makes water be boiled into water vapour, if this part heat does not effectively reclaim, be discharged unit, the efficiency of unit will be very low.After condensing Hot water units changes heating arrangement, the exhaust gas temperature of unit can be reduced greatly, make exhaust gas temperature lower than the dew-point temperature in flue gas, this not only increases the thermal efficiency of unit, and the volume and weight of unit is also little a lot.
Summary of the invention
The purpose of this utility model is to provide one, adopts finned tube heat exchange principle, the condensing Hot water units of design.
The purpose of this utility model is achieved in that condensing Hot water units is primarily of parts compositions such as burner, Fuel-air mixing chamber, combustion front, combustion chamber, first order finned tube exchanger, second level finned tube exchanger, a secondary heat exchanger aquaporin, unit smoking box, unit exhaust opening, unit water inlet, unit delivery port, condensation of water mouth, unit casing and unit bases.Combustion gas and air are sent into fuel mixing chamber and are mixed by burner, after combustion front is lighted, in combustion chamber, do Thorough combustion.Produce a large amount of heats after burning, form high-temperature flue gas.High-temperature flue gas enters first order finned tube exchanger, second level finned tube exchanger successively by combustion chamber, and the heat in flue gas is passed to the water at low temperature in finned tube, flue-gas temperature is reduced by height.The flue gas reduced after temperature enters unit smoking box, by outside unit exhaust opening discharge machine.Water at low temperature is by second level finned tube exchanger water inlet, enter second level finned tube exchanger, again by the first secondary heat exchanger aquaporin, enter first order finned tube exchanger, the first secondary finned tube exchanger and high-temperature flue gas and carry out heat exchange, the temperature of water at low temperature is by low rising, high-temperature-hot-water sends unit, for user by unit delivery port.
Owing to have employed such scheme, just can adopt finned tube exchanger principle, be designed to condensing Hot water units.

Detailed description of the invention
In the drawings, burner 1, by after air and combustion gas mixing, sends into Fuel-air mixing chamber 2, after fuel and air do and fully mix in Fuel-air mixing chamber 2, the metal burning face of being admitted to 3 is lighted, and the fuel after lighting burns and produces a large amount of heats in combustion chamber 4, forms high-temperature flue gas.High-temperature flue gas enters first order finned tube exchanger 6 by combustion chamber, and in first order finned tube exchanger, high-temperature flue gas and water do first time heat exchange, and the temperature of high-temperature flue gas declines, and makes the temperature of water increase.Reduce after the flue gas of temperature gone out first order finned tube exchanger, then enter second level finned tube exchanger 8, with the water entered in the finned tube exchanger of the second level, do second time heat exchange, the temperature of high-temperature flue gas continues to decline, and the temperature of water is promoted.The flue gas reducing temperature enters unit smoking box 10, then discharges outside unit through unit exhaust opening.The bottom of unit smoking box is provided with condensed water delivery port 12, and the condensed water be condensed out in flue gas is discharged outside unit by condensed water delivery port.The water of unit external demand heating is by unit water inlet 5, and enter first order finned tube exchanger and do the heat that heat exchange absorbs flue gas, the temperature of water is enhanced.Through a secondary heat exchanger water channel 7 after water extraction high-temperature, enter second level finned tube exchanger 8, the temperature of water improves further at this.To this water with heating termination.The high-temperature water of heating termination, through unit delivery port 9, discharges unit for user.The all equipment of unit is arranged on unit base 13, and unit outside is provided with unit casing 14, and unit base and unit casing are installed and be connected to form an entirety.
