Course of work example 1：
When combustion heat exchanger 2 will carry out combustion heating water, water valve opening makes flow enter from water inlet 24,31 work of extraction fan
Make, the startup of wind turbine 11, combustion gas enters gas circulation ring body hole 123 from gas inlet hole 121, passes through gas injection stomata 1221 and sprays
To through-hole 12, wind turbine inner cavity is sucked by wind turbine 11, inhales extraneous wind simultaneously also by air inlet hole 1241, induced duct 1242
Enter wind turbine inner cavity, by the stirring of 11 wind wheel of wind turbine by air and combustion gas mixing, is sent mixed gas by connecing shortness of breath pipe 125
Enter combustion chamber 21, combustion heat exchanger 2 is heated by 211 ignition of ignition electrode, rear and smoke after burning walk downward, and pass through
Then cigarette/carbon monoxide/exhaust gas is discharged in the smoke outlet of bottom 23 in heat exchanger channels 22, cigarette/carbon monoxide/exhaust gas enters smoke evacuation
Pipeline body 3 orients external discharge by smoke discharging pipe body 3, and the condensed water of combustion heat exchanger 2 flows into smoke exhaust pipe by smoke outlet 23
Then road body 3 flows into condensed water from the condensate drain outlet 32 being arranged on smoke discharging pipe body 3 and receives box 141, passes through condensed water
Receive the externally discharge again of box 141；Hot water after combustion heating is externally supplied from water outlet 25；When combustion gas is after combustion chamber 21 is burnt
When generating hot gas refluence, 11 exhausting of wind turbine becomes the thrust of thermal current, and the extraction fan 31 on smoke evacuation tube body forms thermal current
Suction, one pushes away the smooth circulation that a suction forms thermal current, walks downward being inhaled under the flare and thermal current after burning, makes combustion heat-exchange
The hypomere of device 2 obtains the hot gas of firepower burning and high temperature, improves the temperature of hypomere, and then obtain using combustion heat exchanger 2 is whole
Uniform heating, hot gas, which expands, after solution is burnt flows backwards, and solves combustion heat exchanger endpiece underheat, what solution generated when burning
Firepower excessively concentrates on combustion chambers burn, and it is excessively high to solve exhaust gas exhaust temperature, and it is too low to solve hot rate of rotation, reduces because of combustion heat exchanger
Combustion vibration noise the advantages that；Blower cover 124 can accelerate the velocity of liquid assets of air, the quickening of air passage rates, can be with
The effective thermal current for preventing burning pours in down a chimney air intake duct, and preventing the expanding gas due to burning from pouring in down a chimney leads to furnace body noise；It is arranging
Extraction fan 31 on smoke pipe body, when extraneous wind pressure can be prevented big by wind-fall fill in smoke evacuation tube body on or external wind press through big blocking
The smoke outlet of smoke exhaust pipe can prevent external wind from entering and force smoke being discharged, ensure that smoke evacuation is smooth by extraction fan；Exhausting
The rotary speed of fan 31 according to the operating power of the openings ratio of gas ratio valve or wind turbine 11 height, by information data feed back by
Controller 5 controls the rotating speed of extraction fan 31, reaches best the problems in heat transfer effect and solution technical background；
Course of work example 2：
When combustion heat exchanger 2 will carry out combustion heating water, water valve opening makes flow enter from water inlet 24, blast switch
102 settings start the wind pressure value of extraction fan 31, wind turbine 11 starts, gas valve is opened, and so that combustion gas is entered from gas inlet hole 121 and fire
Air-flow leads to ring body hole 123, is ejected on through-hole 12 by gas injection stomata 1221, sucks wind turbine inner cavity by wind turbine 11, simultaneously
Also by air inlet hole 1241, induced duct 1242 by extraneous wind sucking wind turbine inner cavity, by the stirring of 11 wind wheel of wind turbine by air
With combustion gas mixing, mixed gas is sent into combustion chamber 21 by connecing shortness of breath pipe 125, is heated by 211 ignition of ignition electrode
Combustion heat exchanger 2, rear and smoke after burning walk downward, and by heat exchanger channels 22, are then discharged in the smoke outlet of bottom 23
Cigarette/carbon monoxide/exhaust gas, cigarette/carbon monoxide/exhaust gas enter smoke discharging pipe body 3, and external discharge is oriented by smoke discharging pipe body 3,
The condensed water of combustion heat exchanger 2 flows into smoke discharging pipe body 3 by smoke outlet 23, then cold on smoke discharging pipe body 3 from being arranged
Condensate floss hole 32 flows into condensed water and receives box 141, and the externally discharge again of box 141 is received by condensed water；Heat after combustion heating
Water is externally supplied from water outlet 25；Wind pressure, which spreads, closes 132 real-time workings, and the pneumatic effect of external environment leads to furnace body air-flow negative direction
Recharge stream or exhaust efficiency occurs and declines or blocks and can not discharge fume, when wind pressure spread pass 132 detect less than setting wind pressure value when,
132 feedback wind pressure value of pass is spread to controller 5 by wind pressure, is controlled by controller 5 and starts extraction fan 31, carry out forced draft row
Wind pressure is spread and closes the raising of 132 values by cigarette, proves that smoke evacuation is smooth when being higher than set wind pressure value, working properly；Work as external environment
When wind negative direction generation recharge stream or blocking can not discharge fume, when the wind pressure of 11 chamber of short time inner blower not up to automatically powers off still
Meeting exhausting, will produce higher and higher wind pressure, since the length of induced duct 1242 is slightly shorter than the height of through-hole 122 in 11 intracavitary of wind turbine
Degree or equal to the height of through-hole 122 or the height of slightly longer than through-hole 122, wind pressure can be such that combustion gas slows down into the speed in wind turbine machine cavity
Degree, meanwhile, the speed that induced duct 1242 enters in wind turbine machine cavity can also slow down, and 1242 nozzle of induced duct occupy wind turbine 11 substantially
Air inlet on, combustion gas is can not be from the adverse current of induced duct 1242, to achieve the purpose that prevent gas leakage, when controller 5 is examined
Measure wind pressure spread close 132 values be less than set shutdown value when, controller 5 automatically powers off, and entire furnace body is stopped, and prevents
Gas leakage and Explosion of boiler proper；So that furnace body air-flow and chamber pressure is stablized by the operating of extraction fan 31, improves the anti-of furnace body
Wind energy power ensures that the operation flameholding of furnace body, the front end arrangement blower cover 124 of injector can accelerate the circulation speed of air
Degree, the quickening of air passage rates, the thermal current that can effectively prevent burning pour in down a chimney air intake duct, prevent the expansion due to burning
Gas, which pours in down a chimney, leads to furnace body noise.
