Abstract
The utility model relates to an air water heat exchanging pressureless boiler which comprises a pressureless boiler and a heat exchanger in the boiler. The heat exchanger in the boiler is composed of a water-water heat exchanger and an air water heat exchanger which are connected in series. The boiler can obviously enhance the water temperature of heating water, and can reliably heat by a natural circulation mode when power is cut off. Boiler water is not mixed with the heating water, and is used as boiled water or bathing water.
Description
The utility model belongs to a kind of normal-pressure hot-water boiler, specifically, relates to a kind of pressure-less boiler that the heat exchange of air water water is arranged.
The water water-to-water heat exchanger is set in the commercially available normal-pressure hot-water boiler, so that supply heating water respectively and drink and water for bathing, as the product of metallic structure factory in the spring of Yangquan, Shanxi, the shortcoming of this boiler is that the heat transfer rate of heat exchanger is low, and the leaving water temperature of heat exchanger is low.
The purpose of this utility model is to design a kind of heat exchange efficiency height, air water water heat exchange pressure-less boiler that the heat exchanger leaving water temperature is high.
Air water water-to-water heat exchanger of the present utility model is made up of heat exchanger two parts in normal-pressure boiler and the stove, it is characterized in that described normal-pressure boiler can be hot-water boiler or hot oil boiler; Heat exchanger partly is that heat exchange of water water and part are the two series connection of air water water heat exchange in the described stove.
Described air water water-to-water heat exchanger is arranged in the water leg of boiler, and flue gas flows through from central tube, and heating water is from clamp sleeve laminar flow mistake, and heating water is heated by boiler water and flue gas simultaneously.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
As shown in the figure, 1 is shell, and 2 is shell and inner bag water leg, and 3 is lower smoke box, 4 is fire grate, and 5 are convection current smoke-box, 6 air water water-to-water heat exchangers, 7 is inner sleeve, and 8 is outer tube, and 9 is upper smoke box, 10 is chimney, and 11 is the water water-to-water heat exchanger, and 12 is burner hearth, 13 is exhaust outlet, and 14 are the smoke box inlet, and 15 are the ash disposal hole, 16 is lower smoke box, and 17 are the smoke box outlet, and 18 is upper smoke box.
As shown in the figure, the flue gas that coal burns on fire grate 4 and produces, a part enters smoke-box 15 from burner hearth 12 rear portions, with discharge by chimney 10 after the convection calandria heat exchange, a flue gas enters lower smoke box 3 from burner hearth 12 both sides, shunting then, the interior and heating backwater heat exchange of each sleeve pipe that enters air water water three stream heat exchangers 6, import upper smoke box 9 at last, enter atmosphere by chimney 10.Heating water is directly entered in the interlayer of air water water-to-water heat exchanger 6 sleeve pipes by inlet, while and flue gas, boiler water heat exchange, its trend and flue gas are in the same way, to upper boiler, flue gas enters smoke box 9, the hot water that heating water enters water water-to-water heat exchanger 11 and upper boiler carries out heat exchange, and is last, and the remittance header tank goes out boiler and enters the user.
Boiler water of the present utility model does not contact with heating water, still can do boiling water of Gong drinking and the hot water of Gong having a bath.During power failure, heating system can with the Natural Circulation heat supply.When the medium of boiler is oil, improve the oil temperature, can improve the utilization ratio of heat exchanger in the stove.
Claims (3)
1, a kind of air water water heat exchange pressure-less boiler is made up of heat exchanger in the stove and pressure-less boiler, it is characterized in that heat exchanger is divided into two parts in the described stove, and a part is the water water-to-water heat exchanger, and a part is the air water water-to-water heat exchanger, and two parts are connected in series.
2, pressure-less boiler as claimed in claim 1 is characterized in that described air water water-to-water heat exchanger is arranged in the water leg of boiler, and flue gas flows through from central tube, and heating water is from clamp sleeve laminar flow mistake, and heating water is heated by flue gas and boiler water simultaneously.
3, pressure-less boiler as claimed in claim 1 is characterized in that described pressure-less boiler is hot-water boiler or hot oil boiler.
