It is flowed out afterwards from the second fire end waterpipe (R2)；
Second, condenser side heat exchange medium by the 8th fire end waterpipe (R8) enter the Recuperative heat exchanger (6) and with
The heat exchange of vaporizer side heat exchange medium, flows out after through third fire end waterpipe (R3)；
The second fire end waterpipe (R2) passes through after mixing with the heat exchange medium that third fire end waterpipe (R3) flows out
5th fire end waterpipe (R5) enters the boiler subsystem (101).
7. system according to any one of claim 1 to 6, it is characterised in that: in the vaporizer side heat exchange medium
Added with desulfurization, out of stock medicament, the vaporizer side heat exchange medium is in the hot and humid area subsystem (102) after spraying
Desulfurization, out of stock effect are generated to flue gas and reach reduction flue dust to reduce the substances such as the sulfide in flue gas, nitrogen oxides
Discharge and the effect for eliminating white cigarette.
8. the system according to any one of claim 3 to 7, it is characterised in that: the water treatment room (3) is situated between to heat exchange
Matter handle and the liquid containing pollutant is discharged after treatment.
9. system according to any one of claims 1 to 8, it is characterised in that: the boiler in the boiler subsystem (101)
For biomass boiler.
10. a kind of control method of -9 described in any item high-efficiency integrated boiler systems according to claim 1, feature exist
In including the following steps:
S1: key position setting in the system monitors sensor and acquires the monitor value of the sensor；
S2: the operation of the system is controlled according to the collected monitor value and by the heat exchange medium, the flue gas of discharge
The state modulator of pollutant is within the set range.
11. according to the method described in claim 10, it is characterized by:
The monitoring sensor include one or more of the temperature of heat exchange medium, flow velocity, pressure, exclude containing pollution
One or more of the temperature of the liquid of object, flow velocity, water quality, the temperature of flue gas, humidity, flow velocity, pressure, soot dust granule object,
One or more of nitrogen oxides, sulfur dioxide concentration.
