Description

Air-supply preheating type hot water boiler
Technical field
The utility model relates to a kind of boiler, especially a kind of air-supply preheating type hot water boiler.
Background technique
Currently, common small size hot-water boiler includes the furnace shell that there is insulating layer in outside, run in smoke pipe on furnace shell top, in furnace shell Side lower part is equipped with grate, is terminated with pedestal under furnace shell, is equipped with liner in the inside of furnace shell, forms annular between liner and furnace shell Water jacket, water jacket is connected with water inlet tap and faucet, and water inlet tap is connected by pipeline, valve, water pump with water supply device, faucet Connected by pipeline, valve, water pump with hot water user.It is located at grate top in furnace shell and forms combustion chamber, is cigarette above combustion chamber Wind apparatus is picked in room, combustion chamber.Fuel is sent on grate from the fire door of furnace shell side, and the heat that when burning generates will be in water jacket Water heating.Also some replaces water jacket with arrangement furnace tube mode in furnace shell.The boiler of this structure is by sending at runtime Air in atmosphere is sent directly into furnace by wind apparatus, and the gas temperature being sent into furnace is environment temperature, and winter is sent into furnace Air themperature is lower, has an impact to combustion chamber, plays the role of reducing chamber temperature, waste of energy.
Summary of the invention
The purpose of the utility model is to provide a kind of structures, and wind that is simple, being sent into furnace can preheat in advance, improve air-supply temperature Degree, the air-supply preheating type hot water boiler for reducing the low influence generated to furnace inner combustion chamber of inlet air temperature, saving the energy, overcome existing The deficiency of technology.
The air-supply preheating type hot water boiler of the utility model, including furnace shell and air supply device are equipped with heat preservation on the outside of furnace shell Layer, lower part is equipped with grate in furnace shell, and combustion chamber is formed above grate, is smoke-box above combustion chamber, have above smoke-box on furnace shell The smoke exhaust pipe to connect is held, there is pedestal in furnace shell lower end, has bushing in furnace shell, form water jacket between bushing and furnace shell.In smoke-box Air supply tube equipped with reciprocating and turning-back shape, one end of air supply tube reach outside furnace shell and connect with the exhaust outlet of air supply device, send The other end of air hose reaches outside furnace shell and connects with the upper end of vertical tube, and vertical tube is located at the outside of the insulating layer, vertical tube Lower end connects with the air inlet on furnace shell side, and air inlet is located at the top of the grate, and thermal insulation layer is equipped on the outside of vertical tube.
The air-supply preheating type hot water boiler of the utility model, the wind sent out when operation through air supply device initially enter smoke-box It is interior, it is heated in smoke-box and improves its temperature, then enter combustion chamber through vertical tube, make to be higher than atmospheric temperature into the indoor wind that burns, Influence of the inlet air temperature to chamber temperature is reduced, the energy can be saved after improving inlet air temperature, be effectively utilized in smoke-box Heat, wind that is simple with structure, being sent into furnace can preheat in advance, it is low in furnace to improve supply air temperature, reduction inlet air temperature The advantages of energy, is saved in the influence of combustion chamber generation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific embodiment
The air-supply preheating type hot water boiler of the utility model as shown in Figure 1:, including furnace shell 3 and air supply device 10.In furnace shell 3 outsides are equipped with insulating layer 2.Lower part is equipped with grate 13 in furnace shell 3.Combustion chamber is formed above grate 13, is smoke-box above combustion chamber 6, there is the smoke exhaust pipe 7 to connect with 3 upper end of furnace shell above smoke-box 6.There is pedestal 1 in 3 lower end of furnace shell.There are bushing 4, bushing 4 in furnace shell 3 Water jacket 5 is formed between furnace shell 3.The air supply tube 8 of reciprocating and turning-back shape is equipped in smoke-box 6, one end of air supply tube 8 reaches furnace shell 3 outsides simultaneously connect with the exhaust outlet of air supply device 10.The other end of air supply tube 8 reaches outside furnace shell 3 and upper with vertical tube 14 End connects, and vertical tube 14 is located at the outside of insulating layer 2, and the lower end of vertical tube 14 connects with the air inlet 12 on 3 side of furnace shell.Air inlet 12 are located at the top of grate 13.Thermal insulation layer 11 is equipped on the outside of vertical tube 14.
The air-supply preheating type hot water boiler of the utility model, the wind that when operation is sent out through air supply device 10 initially enter smoke-box It in 6, is heated in smoke-box 6 and improves its temperature, then enter combustion chamber through vertical tube 14, make to be higher than big temperature into the indoor wind that burns Degree reduces influence of the inlet air temperature to chamber temperature, can save the energy after improving inlet air temperature, smoke-box is effectively utilized Heat in 6, wind that is simple with structure, being sent into furnace can preheat in advance, it is low to furnace to improve supply air temperature, reduction inlet air temperature The advantages of energy, is saved in the influence of inner combustion chamber's generation.
