And the described fire hole wall that turns over is built into by refractory brick, is shaped with 4-6 on it and arranges square smoke intaking hole.
And described venthole wall is built into by refractory brick, is shaped with 7-10 on it and arranges circular venthole.
And described serpentine heat exchanger is the 25-40 group.
And described heat exchanger stay pipe is 4-6 hollow metal pipe, and the one end opening is communicated with atmosphere, other end sealing.
And, be shaped with 3-5 outlet flue on the described collection smoke box.
Advantage of the present utility model and good effect are:
1, this energy-saving steam pipe oven by the design of the inner 25-40 group of body of heater serpentine heat exchanger, has increased the contact area of heat exchanger and furnace gas, makes heat exchange more efficient.
2, this energy-saving steam pipe oven by being the metal pipe structure that an end of hollow is communicated with atmosphere with design of heat exchanger, is conducive to the cooling of self, increases the service life.
3, this energy-saving steam pipe oven, design by burner top temperature adjustment through hole, the cold wind that makes the interior furnace gas that produces of burning cavity can rely on the temperature adjustment through hole to enter is regulated its temperature, and the heat exchanger of having avoided causing owing to the excess Temperature that enters in the body of heater damages problem.
4, this energy-saving steam pipe oven, by turning over the design of circular venthole on the square smoke intaking hole and venthole wall on the fire hole wall, it is fast that the velocity ratio that makes furnace gas advance body of heater goes out the speed of body of heater, prolonged the time of staying of furnace gas in body of heater, take full advantage of the heat of furnace gas, reduce consuming.
5, this energy-saving steam pipe oven, scientific structure design is reasonable, has that the realization of being easy to, long service life, production efficiency are high, low power consumption and other advantages, is a kind of energy-saving steam heating furnace with higher innovation.
