Step 2: Electric air valve adjusts mixed blower frequency after opening, regulate and control burner hearth hot blast temperature immediately, make burner hearth constant temperature 800
DEG C, high-temperature hot-air enters cyclone separator through horizontal burner hearth, and the flue gas after separation enters combustion generator by high temperature smoke pipe
In group；
Step 3: combustion generator group selects multiple groups thermal energy to shake combustion generator, and the thermal energy concussion combustion generator is in parallel
Or concatenation completes the heat absorption power generation of generator, high-temperature flue gas is through shunting burner hearth point by shunting burner hearth air inlet, plenum chamber return air
Stream gives generator heat supply, by plenum chamber afflux；
Step 4: after absorbing heat via generator, hot wind flows through flue gas energy saver, the overwhelming majority in flue gas energy saver recovered flue gas

It is interior, after forming spiral vortex between the inner walls and exhaust tube wall of cyclone separator, makes rotating motion downwards, be centrifuged
Under the action of power, grit reaches inner walls and under lower rotational gas flow and gravity collective effect, falls into depositing dust along wall surface and captures ash
Bucket, purified gas are excluded through air draft port；
Thermal energy in the step 3 shakes combustion generator, by absorbing external heat source thermal energy, is converted into generator point
Son concussion passes to the power generation of straight line reciprocating motion of the pistons cutting magnetic induction line；
Flue gas energy saver in the step 4 does heat transfer element using fin, is returned by the heat that heat exchange carries flue gas
It receives, heats another transfer --- water, reach energy-saving and environment-friendly purpose.
