7.5t/h Waste Heat Boiler is designed for vertical natural circulation waste heat boiler. The heat is flue gas discharged hazardous waste incineration

Features of 7.5t/h Waste Heat Boiler is:

1.energy-saving to achieve thermal energy utilization. Waste Heat Boiler is to use micro-dust concentration in flue gas remaining heat of waste recycling systems can be used for power generation, production, life of superheated steam.It does not use disposable fuel, so it has the characteristics of energy-saving and comprehensive utilization of energy.

2.furnace dust. it is conducive to environmental protection.

Due to the flue gas contains large amounts of coarse dust, the boiler uses combined inertia separation principle and gravitational separation principle to achieve separation of dust, reducing soot content.

3. low resistance, running economy.

Waste Heat Boiler heating surface by adjusting the flow rate of flue gas flow cross-sectional area to achieve the design, reducing the bulk resistance, conducive to the integration with other devices and reduce system power consumption.

4. compact.it looks neat in appearance.

Design features of 7.5t/h Waste Heat Boiler

7.5t/h Waste Heat Boiler is verticalnatural circulation. The heat from the boiler is flue gas which is discharged from hazardous waste incineration. Boiler feed water temperature is 104 ℃.Working fluid directly into the drum, and then from the drumdown pipe flows through the membrane wall, where after being heated steam conduit reintroduction drum, and then separated by soda leads to saturated steam from the steam drum.

7.5t/h Waste Heat Boiler heating surface adopts membrane wall structure, the pipe diameter is Φ60. Membrane wall is left on the hole, blowing holes . the user adopts sootblowers according to specific circumstances. Boiler furnace wall select light furnace wall.

Structure introduction of 7.5t/h Waste Heat Boiler

1.Drum

Drum diameter isФ1500.Material of drum is 20g.The main equipment in the boiler is underwater plate,corrugated plate separator,feed water system and so on. Soda mixture come into the drum, first by underwater plate, and then further separation by the corrugated plate separator, after that it lead out.

2. Evaporating heating surface is composed by the inlet and outlet header and the membrane wall.The header is made ofФ219 steel tube. The membrane wall is made ofФ60 tube and welded steel.

3.boiler pipes

The boiler drum installs safety valve, pressure gauge,water table, continuous blowdown, dosing valve and so on.

4.furnace wall

This boiler adopts light furnace wall.So as to improve boiler effiency,reduce furnace wall leakage,reduce heat loss from the boiler.The drum insulation thickness is about 100-120mm. All leads, down tube and pipe insulation thickness is 80mm.The material is calcium silicate insulation coating.

5. water quality and export steam quality requirements.
Boiler feed water and boiler water indicators should be consistent GB1576-2001.
