Description
Technical field
The present invention relates to a kind of heating boiler, the energy-saving efficient boiler that particularly a kind of coal utilization rate is high, thermal conversion rate is high.
Background technology
Coal-burning boiler is the heat transmission equipment of life, production field extensive use, is that high-temperature flue gas and the water that produces during by coal combustion carries out heat exchange, to provide high-temperature steam or hot water as purpose.The shortcomings such as present coal-burning boiler ubiquity coal utilization rate is low, the discharging smoke pollution is strong are accelerated the consumption of coal resources and the deterioration of environment.Trace it to its cause and be mainly:
At first, air transport device can't satisfy in the coal burning process demand to air; Because coal can't fully burn in burner hearth, portion of energy can not change into heat energy, and existing commonly used processing method is the cross-sectional area that reduces boiler, and required air when satisfying coal burning has directly reduced the operating efficiency of boiler; Therefore, how solving the air conveying is urgent problem;
Secondly, the high-temperature flue gas quick migration that makes progress, little and the time is short with the water layer contact area, the heat energy in flue gas fails fully to be absorbed by water layer; By completing in smoke-fire-tube, smoke-fire-tube length is longer due to the heat exchange of high-temperature flue gas and water, and heat exchange is more abundant, but thermal losses is larger; Therefore, how effectively improving heat exchange is also urgent problem;
Again, high-temperature flue gas carries a large amount of remaining cigarettes and is discharged by flue, causes air pollution; Due to high-temperature flue gas migration speed, the coal burning dust that carries in high-temperature flue gas will be carried ejection, and air is caused severe contamination;
At last, coal is in combustion process, and primary combustion can't be thoroughly with coal burning totally, can produce a large amount of dust rubbish, therefore need to be to the process of fuel design second-time burning, thus when solving the fuel combustion dust, carrying out fully to fuel, burning improves fuel availability.
Summary of the invention
The technical problem to be solved in the present invention is that the air in the coal burning process is carried, the area of high-temperature flue gas and water layer heat exchange, and high-temperature flue gas carries the air pollution that dust causes, and coal fully burns.
For solving described problem, the open energy-saving efficient boiler of the present invention comprises boiler body, heat exchanging pipe and burner hearth; Wherein, described boiler body comprises shell, inwall and heating tube, shell is the cylinder that the middle part has lighting-up tuyere, and inwall is that the middle part is provided with pot cylinder of shape structure, is positioned at the lighting-up tuyere top with shell concentric socket and a pot shape structure, is water tank between inwall and shell; Described heating tube is arranged at the shell top, is connected with water tank; Described heat exchanging pipe comprises feed pipe and smoke-fire-tube, many smoke-fire-tubes of socket in feed pipe; Described burner hearth middle part has the mouth of delivering coal; Its annexation is: described heat exchanging pipe one end is arranged at ground, and the other end connects the upper limb of shell, and the smoke-fire-tube of the heat exchanging pipe other end stretches in boiler body and is connected with burner hearth; Described boiler body is arranged on the burner hearth that is positioned at ground;
It is characterized in that: described energy-saving efficient boiler also comprises fuel supply system and air output device; Described fuel supply system comprises fuel supply pipe and motor; Described fuel supply pipe comprises outer tube and inner tube, and outer tube extends forward and front end makes progress, and bending is horn-like, and the inner tube socket is interior with outer tube, inwall arranges the front impelling sheet of screw; Motor is connected with inner tube; Described fuel supply pipe is inner by mouthful insertion burner hearth of delivering coal;
Described air output device comprises arcuation cooling outer tube, air inlet, ajutage and wind pushing hole, the first half of described arcuation cooling outer tube and air outlet is tightly connected, and have ajutage between the first half of arcuation cooling outer tube and air outlet, the top of described ajutage has wind pushing hole; The two ends of described arcuation cooling outer tube are connected with water tank respectively; Described air output device coupling is fixedly installed on the top of fuel supply pipe outer tube.
