Gas east is defeated " realization of engineering, gas fired-boiler has been increasingly becoming the first choice of people.
Gas-steam boiler refers to be heated using fuel gas buring, and burn the heat released in furnace, the water in heating kettle,
And it is made to be vaporized into the thermal energy conversion equipment of steam.Water is in pot（Drum）In constantly released by gas fuel combustion in furnace
Energy warms temperature increases and generates pressurized vapor.Since the boiling point of water is increased with the raising of pressure, pot is sealing, and water steams
The expansion of gas inside is restricted and generates pressure initiation heat power, and strictly speaking the vapor of boiler is that water is fixed in drum
Pressure is heated to saturated water and re-vaporizes to be formed, and is widely used as a kind of energy.
But existing gas-steam boiler, the heat in combustion chamber carry out heat exchange, heat to the water in drum with flue gas
Flue gas after exchange is expelled directly out, and the exhaust gas temperature of general gas steam boiler wastes the remaining of flue gas in 180 degree or so significantly
Heat causes the waste of resource.
Summary of the invention
The purpose of the utility model is to provide a kind of energy-saving gas steam boilers, to solve fume afterheat quilt in the prior art
The problem of waste.
To achieve the above object, a kind of energy-saving gas steam boiler of the utility model adopts the following technical scheme that：It is a kind of

Including water tank, it is provided with the heat exchanger tube passed through for flue gas for being connected to heat-exchanger rig in water tank, is provided with cold water on water tank
Import and hot water outlet, hot water outlet are connected to by connecting tube with drum, and connection tube valve and connecting tube are provided in connecting tube
Water pump.
The hot water outlet includes the first hot water outlet and the second hot water outlet, and connecting tube is connect with the first hot water outlet,
It is connected with outlet pipe on second hot water outlet, water outlet tube valve is provided on outlet pipe.
The heat exchanger tube is coiled pipe or coil pipe.
It is provided with water-level gauge in the drum, which further includes the controller connecting with water-level gauge signal,
Controller and the connecting tube water pump and connection tube valve control are connected with automatic when water level needs moisturizing in detecting drum
It opens connecting tube water pump and connection tube valve is automatically replenished.
Water thermometer is provided in the water tank, water thermometer is connect with controller signals, and water outlet tube valve and controller control
Connection.
It is provided with the exhaust tube for being connected to heat exchanger tube on the water tank, is provided with silencing means on exhaust tube.
The carbon dioxide supplementary set device for being connected to heat exchanger tube is provided on the water tank.
The beneficial effects of the utility model：The fume afterheat carried out after heat exchange with the water in drum adds the water in water tank
Heat, when the water in drum becomes steam and is discharged by passing through the steam-water separator above drum, the water in drum will tail off,
When needing moisturizing in drum, the hot water in water tank can be added to replace that cold water is added into drum in drum at this time, saved
The heat of cold water heating is saved, and the hot water in the water tank being added is the preheating heating by flue gas, is effectively utilized flue gas
Preheating, energy-saving and emission-reduction.
