Description
Technical field
The utility model relates to a kind of water cooling to premix steam generator, belongs to steam generating equipment technical field.
Background technology
Steam generator of the prior art, its combustion system mainly use traditional fire grate type diffusion combustion, and big portion
It is divided into without pressure or negative-pressure firing.Simultaneously not to scale (NTS) is fully premixed with air for combustion gas before burning, but side mixes at fire row nozzle
Side is burnt, combustion gas because undercompounding cause can not completely burned, flame temperature is low, and excessive air coefficient also reduces
Its thermal efficiency, causes combustion gas to waste.Not sufficiently combusted exhaust gas damages environment and health care belt, in combustion process security compared with
It is low;And fire row volume is big, the stroke for the needs that burn is grown, and inevitably increases the volume of steam generator.
And the mixing of premix combustion combustion gas is more abundant, but mixed since combustion gas is in before burning is started with air
The incendivity state of conjunction, easily produces tempering and opposite confined space ignition deflagrating of hot, brings security risk in this case.In order to
Solve the problems, such as this, someone is used as combustion head using porous ceramic plate in the prior art, but the stability difference of ceramic wafer material is mechanical
Intensity is low, and percent opening is low, and metal shell combination poor sealing, often occur in use ceramic wafer burst and weathering,
Service life is low, so that tempering and opposite confined space ignition deflagrating of hot cannot be solved the problems, such as thoroughly.
It is remaining in flue gas and the most steam generator of in the market, high-temperature flue gas are expelled directly out after exchanging heat with water
Heat cannot be used effectively, in order to improve the utilization rate of fume afterheat, in the prior art someone utilize flue gas waste heat pair
Water inlet is preheated, but its combustion head uses fire grate type diffusion combustion, causes to burn insufficient, and increase steam generator
Volume, easily forms incrustation scale in liner after steam generator long-time use, the presence of incrustation scale reduces the area of heat exchange, makes
The gas quantity increase that same steam is consumed must be produced, brings the waste of gas and water, electricity, and incrustation scale can cause interior gallbladder break.
The content of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is reasonable to provide a kind of structure composition, makes
With convenient and reliable, service life length, the formation of incrustation scale, raising heat exchange efficiency, the obvious water cooling premix of energy-saving effect can be reduced
Steam generator.
The purpose of this utility model is completed by following technical solution, and a kind of water cooling premixes steam generator, it
Water cooling premix burner including being provided with cooling water pipe among one, is provided with the front burner hearth of the water cooling premix burner
Direct current spiral heater, the water inlet pipe mouth of the direct current spiral heater is connected on a phase-change type shell-and-tube heat exchanger, and passes through one
Feed pump connects water feeding tank;The effluent pipe mouth of the direct current spiral heater connects a steam-water separator, the steam-water separator
Top is provided with steam (vapor) outlet, and lower sides are by a drain valve through the water pipe connection water feeding tank.
As preferred:The cooling water pipe is connected with the shell side of phase-change type shell-and-tube heat exchanger, and makes cooling water pipe and phase
The heat medium water circulated is filled with the case where keeping vacuum state in the shell side of variant shell-and-tube heat exchanger;The direct current coil pipe heating
The water inlet pipe mouth of device is located at the bottom of burner hearth, and the effluent pipe mouth of the direct current spiral heater is located at the front end of burner hearth;
The water inlet pipe mouth of the direct current spiral heater is connected with the tube side of phase-change type shell-and-tube heat exchanger, and by the tube side through feedwater
The pump connection water feeding tank.
The utility model belongs to improvements over the prior art, it has, and structure composition is reasonable, easy to use and reliable, uses the longevity
The features such as life length, can reduce the formation of incrustation scale, improve heat exchange efficiency, and energy-saving effect is obvious.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
The utility model is described in detail below in conjunction with attached drawing:Shown in Fig. 1, a kind of water described in the utility model
Cold premixing steam generator, it includes being provided with the water cooling premix burner 2 of cooling water pipe 1 among one, the water cooling premix combustion
Direct current spiral heater 3 is installed, the water inlet pipe mouth 4 of the direct current spiral heater 3 is connected on one in the front burner hearth of burner 2
Phase-change type shell-and-tube heat exchanger 5, and water feeding tank 7 is connected by a feed pump 6;The effluent pipe mouth 8 of the direct current spiral heater 3 connects
A steam-water separator 9 is connect, the top of the steam-water separator 9 is provided with steam (vapor) outlet 10, and lower sides are passed through by a drain valve 11
