Abstract
The utility model relates to a coal furnace for generating hot water, boiled water and steam, mainly composed of a furnace chamber (1), a furnace grate (2), a smoke channel (4), a hot water tank (6), and a boiled water tank (7). A communicating pipe (8) is used for communicating between the hot water tank (6) and the boiled water tank (7). The utility model has simple structure, can automatically feed water, continuously supplies the hot water and the boiled water, can effectively supply the steam, and can be used for cooking or heating. When the steam has no need of supplying and the consumption of the boiled water is less, the steam is used for heating the hot water, and the energy resource is fully utilized.
Description
The utility model relates to a kind of water heater with thermal source, specifically, is a kind of coal-fired do not have (low pressure) hot water of pressure, boiling water, steam oven.
Existing drinking water boiler (referring to CN88203587.U), have boiler, boiled water tank and water supply tank, boiler has communicating pipe to give the boiled water tank moisturizing from top to bottom, because communicating pipe, the lower end linked to each other with boiled water tank, the upper end links to each other with boiler, the water temperature of lower end is higher than the water temperature of upper end, forms convection current, the boiling water in the boiled water tank constantly with boiler in hot water exchange.In order to overcome above shortcoming, existing drinking water boiler all is equipped with check-valves on communicating pipe, and check-valves has avoided the boiling water of boiled water tank to flow to boiler.
CN94242200.7 discloses the hot boiler of a kind of coal-fired energy-saving, it relatively simple for structure, it is that a double take-off valve was housed on communicating pipe, with the flow direction of water and vapour between control boiler and the boiled water tank, and can make full use of hot water in the Steam Heating boiler of boiled water tank.
But above two kinds of drinking water boilers have all used valve, thereby have improved manufacturing cost, and in a single day valve breaks down, and just produces unsafe factor.
The utility model is the improvement of utility model CN94242200.7.The object of the present invention is to provide a kind of structure simpler, safer, and the fire coal of energy effective supply steam does not have pressure (low pressure) hot water, boiling water, steam oven.
The utility model is finished by the following technical programs.
Hot water of the present utility model, boiling water, steam oven is by burner hearth (1), fire grate (2), fire door (3), flue (4), chimney (5), boiler (6) and boiled water tank (7) are formed, flue (4) runs through boiled water tank (7) and boiler (6) and mistake, boiler (6) communicates with atmosphere, the automatic water-replenishing device that links to each other with running water pipe is housed in boiler (6) and controls water level, on boiler (6) and boiled water tank (7), the halter that discharges water is housed respectively, between boiler (6) and boiled water tank (7), there is communicating pipe (8) to be communicated with, the height of communicating pipe (8) and boiled water tank (7) connecting place (9) is lower than the height of water level in the boiler (6), and the height of communicating pipe (8) and boiler (6) connecting place (10) is lower than 20 centimetres of the height of communicating pipe (8) and boiled water tank (7) connecting place (9) at least.
For the heat that makes burner hearth (1) makes full use of, burner hearth (1) is except that fire grate (2) and fire door (3) direction, and remainder is all surrounded by water tank, and fire door (3) is located at the front of burner hearth (1).Scatter and disappear for reducing heat, tank outer wall is surrounded by heat-insulation layer.
Hot water of the present utility model, boiling water, when steam oven adds water, the water replanishing device of running water in boiler (6) enters boiler (6), reach the height of communicating pipe (8) and boiled water tank (7) connecting place (9) when water level after, water in the boiler (6) enters boiled water tank (7) through communicating pipe (8), up to the water level arrival setting height of boiler (6) with boiled water tank (7), the water replanishing device valve-closing stops moisturizing.In burner hearth (1), burn coal, heating water tank, flue gas also heating water tank when the flue (4), water in the boiler (6) is heated up, water in the boiled water tank (7) is boiled because boiler (6) is to give boiled water tank (7) moisturizing from bottom to top, communicating pipe the water temperature of (8) lower end be lower than the water temperature of upper end, avoided convection current, guaranteed that the water temperature of boiling water in the boiled water tank (7) does not reduce.The halter that discharges water of the discharge water halter and the boiled water tank (7) of boiler (6) can emit hot water respectively and boiling water uses.Hot water and boiling water are emitted the back water level and are reduced, and the water replanishing device in the boiler (6) starts, and give boiler (6) moisturizing again, and boiler (6) replenishes hot water through giving boiled water tank (7) communicating pipe (8).When the boiling water consumption more after a little while, boiling water in the boiled water tank (7) is heated to form steam, pressure in the boiled water tank (7) raises, boiling water in boiled water tank this moment (7) flows into boiler (6) through communicating pipe (8), after the water level in the boiled water tank (7) is lower than junction (9) with communicating pipe (8), steam in the boiled water tank (7) constantly feeds boiler (6) through communicating pipe (8), and the hot water in the heat hot water tank (6) is fully utilized the heat of fire coal.For the steam that makes feeding can be absorbed fully, can stretch into communicating pipe (8) in the boiler (6); In order to make the hot water of mending in the boiled water tank (6) that higher temperature be arranged, communicating pipe (8), the opening part in boiler (6) should be near flue (4), opening part can be connected with a plectane, plectane is parallel with walling of flue, communicating pipe (8) is opened on the plectane center, make to enter communicating pipe the hot water of (8) all passes through flue (4) heating, enter boiled water tank (7) with higher temperature to guarantee the hot water in the boiler (6).
Hot water of the present utility model, boiling water, steam oven can be equipped with the flue gas adjustment doors on chimney (5), to regulate intake, the combustion position of fire coal in the control burner hearth (1).
Hot water of the present utility model, boiling water, steam oven can be drawn steam outlet tube (11) at boiled water tank (7) top, and steam outlet tube is equipped with valve on (11), can supply with vapour cooking or heating.Since communicating pipe (8) the junction (9) of boiled water tank (7) with in boiler (6) junction (10) difference in height is arranged, so in the boiled water tank (7) certain pressure can be arranged, can supply with steam effectively.If in the time of need producing more quantity of steam in the unit interval, can load onto heat pipe in burner hearth (1) and flue (4), the increase heat transfer efficiency strengthens out quantity of steam.
Hot water of the present utility model, boiling water, steam oven, simple in structure, cost is low, can supply with hot water and boiling water continuously, supplies with steam effectively, and can automatic water supplement.Less when the boiling water consumption, boiling water is burnt till steam, if do not need to supply with steam, steam can be used to heat hot water, and heat is fully utilized, thereby has improved the utilization rate of burning coal, has saved the energy.Between boiler and boiled water tank,, there is not valve only with being connected communicating pipe, therefore safer.
