Along with energy problem and problem of environmental pollution become the focus that the whole world is paid close attention to, people press for the high efficiency digesting apparatus of a kind of low power consuming.Catering industry is the high energy consumption industry, need consume a large amount of heat energy every day and be used for cooking and dish.And exhausted most restaurant, street restaurant come cooking with the water generates steam in the direct heating kettle of stove, because the moisture storage capacity of pot is big, heat-exchange surface is little, certainly will cause that temperature rise is slow, the thermal efficiency is low, and energy waste is serious.Particularly when intermittently using, must constantly heat, in tempus intercalare, waste fuel especially in vain to keep the yield rate after the normal steam amount is accelerated to have a rest.The waste of fuel not only increases operator's cost, and has caused non-renewable energy waste and environmental pollution.
Summary of the invention
At the problems referred to above of present catering industry existence and people's needs, the purpose of this utility model is to provide a kind of small-sized combustion and steam generating means, this steam raising plant heat-transfer surface is big, thermal efficiency height, moisture storage capacity is little, steams fast, it is stable to go out vapour, and safe and reliable, compact conformation is particularly suitable for the catering industry boiling and uses.
For achieving the above object, the utility model provides a kind of small gas steam generator, it comprises shell and is located at shell interior burner, storage tank, steam (vapor) outlet is in cover top portion, and burner connects the gas inlet pipe road, also is connected with ignition switch, control device on it, storage tank is connected with inlet pipeline, pipeline is provided with water level and limits valve, and the storage tank bottom that is located at burner top is provided with flue to projecting inward formation combustion chamber between combustion chamber and the storage tank.
Described flue comprises around the skin of combustion chamber and is provided with inner flue between the sidepiece and storage tank shell, and communicates with top of combustion chamber institute perforate, is provided with exhaust steam passage between inner flue bottom and the storage tank shell; Establish external flue around the storage tank shell, external flue is communicated with exhaust steam passage, and external flue is communicated with the negative pressure air exhauster.
Between described inner flue and combustion chamber and the tank shell certain distance is set, is provided with many backhauls demarcation strip that hot waste gas is flowed by the direction of setting in the inner flue, the bottom of combustion chamber is connected with the outer casing underpart of storage tank.
Top of combustion chamber has a hemispherical recess, is provided with the ball float that is used for hydrous water locator qualification valve in the hemispherical recess.
As mentioned above, as can be seen, the small gas steam appliance that the utility model provides has following advantage:
1, because combustion chamber and inner flue are arranged in the storage tank, reduced the storage tank volume, moisture storage capacity is reduced, and external flue connection storage tank shell, increased heat-transfer surface, so the thermal efficiency of steam generator is higher, save the energy and produce steam fast;
2, because top of combustion chamber has the ball float of hemispheric recess hydrous water locator qualification valve, make the water in the heat exchanger can each heating surface of submergence, unlikely again overfill has reduced water storage;
3, because external flue is connected to the negative pressure air exhauster, make the waste gas in the flue flow and form turbulent flow, and turbulent flow can fill hot waste gas with walling of flue part to contact, strengthened heat exchange effect to direction initialization, waste gas can fully be discharged outside the combustion chamber again.
4, owing in flue, be provided with many backhauls demarcation strip interlayer, increased the time of staying and the turbulent flow of flue gas, the heat exchanger effectiveness height.When flue gas stopped to heat, interlayer had slowed down water tank and extraneous rate of heat exchange, and its exhaust mouth has reduced the loss of heat all down simultaneously.Can effectively save the energy.
