Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the disclosed low-heat radiant boiler of the utility model, comprise furnace shell 1, combustion chamber 2, hot water jacket 3, helical heating pipe 4, hot hydroecium 5 and outlet flue 6, described hot water jacket 3 depends on furnace shell 1 inwall, described helical heating pipe 4 is all positioned at furnace shell 1 with hot hydroecium 5, described hot water jacket 3 bottoms are provided with water jacket water inlet 301, top is provided with water jacket delivery port 302, described water jacket water inlet 301 is connected with boiler water inlet pipe 9, described water jacket delivery port 302 is communicated with helical heating pipe 4, described hot hydroecium 5 is provided with hot hydroecium's water inlet 501 and hot hydroecium's delivery port 502, described hot hydroecium water inlet 501 is communicated with helical heating pipe 4, described hot hydroecium delivery port 502 is connected with boiler discharging tube 10, described hot hydroecium 5 is positioned at helical heating pipe 4 tops, described combustion chamber 2 is positioned at helical heating pipe 4 belows, described outlet flue 6 is positioned at furnace shell 1 top.
Wherein, water jacket water inlet 301 is the water inlet of whole boiler, and hot hydroecium's delivery port 502 is the delivery port of whole boiler.Use this boiler, cold water injects from boiler water inlet pipe 9, after tentatively being heated in hot water jacket 3, enter helical heating pipe 4 from water jacket delivery port 302, water can be heated fast and fully in helical heating pipe 4, finally enter hot hydroecium 5 and further heat, the hot water after heating is sent boiler by boiler discharging tube 10.Hot hydroecium 5, except water is further heated, can also store and insulation hot water, to meet sudden a large amount of water.Water jacket water inlet 301 is arranged at hot water jacket 3 bottoms, and water jacket delivery port 302 is arranged at hot water jacket 3 tops, and making cold water enter hot water jacket 3 later can be by abundant preheating.And hot water jacket 3 is in preheating water, can effectively prevent that heat from spilling into the external world, because water temperature is lower in hot water jacket 3, so that it is radiated extraneous heat energy is also little, thereby improve the utilization rate of heat energy.
In such scheme, if the upper and lower spiral coil of helical heating pipe 4 is in the same size, make top body because blocked by bottom body and can not obtain sufficient heat energy, so, as optimal way, described helical heating pipe 4 spiral coil from bottom to top reduces successively.So the top body of helical heating pipe 4 also easily obtains the heating of abundant heat energy for water, so can shorten the heat time of water, improves the utilization rate of heat energy.
Improve the thermal efficiency of boiler, need to make fuel fully burning in boiler, so, as optimal way, described hot hydroecium 5 is cylindrical shape, and described hot water jacket 3 inner surface tops are dome-shaped, described outlet flue 6 is positioned at the oblique upper of hot hydroecium 5, on 2 sidewalls of described combustion chamber, is provided with air inlet 7.Hot water jacket 3 inner surfaces described here refer to that it is positioned at the one side of stove.Burn in combustion chamber 2 flue gas that produces of fuel carries a large amount of heat energy and the gas such as clean-burning CO not, the through hole of flue gas in the middle of cylindrical shape hot hydroecium 5 passes, hot water jacket 3 inner surface tops by dome-shaped stop, part of smoke will flow downward from hot hydroecium's 5 surroundings, can be by a part of thermal energy transfer in flow of flue gas process to hot water jacket 3 for preheating cold water, in the time that dirty flow of flue gas arrives combustion chamber 2, mix with the air entering from combustion chamber 2 sidewall air inlets 7, mixed flue gas is fully burnt in combustion chamber 2; And unnecessary flue gas can be discharged from outlet flue 6, to enter from the air inlet 7 of combustion chamber 2 sidewalls containing the fresh air of a large amount of oxygen, ensure the oxygen that furnace air contains enough support burnings.Outlet flue 6 is positioned at the oblique upper of hot hydroecium 5, to prevent that the not clean-burning flue gas passing is directly discharged from boiler in the middle of hot hydroecium, wastes energy, and contaminated environment.This scheme can make the fuel oxidizing fire fully in combustion chamber 2, thereby reduces the discharge capacity of harmful smoke, improves the thermal efficiency of boiler.
Due to the positional factor of fuel combustion, the flue gas upwards flowing from combustion chamber 2 surroundings may affect flowing of the above-mentioned flue gas flowing downward from hot hydroecium's 5 surroundings, for addressing this problem, on the basis of such scheme, as optimal way, between described helical heating pipe 4 and combustion chamber 2, be provided with fire conduction plate 8, described fire conduction plate 8 is dome-shaped, fire conduction plate 8 centers offer leading fire hole 801, and described leading fire hole 8 surroundings offer some pairs and lead fire hole 802.Wherein, leading fire hole 801 is larger, and that pair is led fire hole 802 is less, and the flue gas so rising from combustion chamber 2 can more concentrate on medium position, be conducive to it helical heating pipe 4 is heated, and don't can affect surrounding flue gas and flow downward and enter combustion chamber 2 and carry out second-time burning.
If sidewall of combustion chamber only arranges an air inlet, may make inner flue gas of the stove flow inhomogeneous, so, on the basis of such scheme, as optimal way, on 2 sidewalls of described combustion chamber, be at least provided with two air inlets 7, each air inlet 7 is uniformly distributed in combustion chamber 2 surroundings.So, the air entering in air inlet 7 will with dirty flue gas effect in stove, make furnace air evenly well flow.
