Water circulation utilizes a combination of forced and natural circulation；Boiler's internal devices are rationally arranged to ensure the medium flowing in the tubes of a single loop will not cause steam and water to boil, with water velocity reasonable, safe and reliable.
2. Flue gas is controlled at around 10m/s, Adjacent tubes in convection tube bundles are connected with stainless steel flat bars to increase tube rigidity and prevent vibration during flue gas scouring. Guide plates are installed at flue bends to eliminate vibration during boiler operation.
3. Economizer (condenser) adopts patented technology with independent intellectual property rights, taking into account both heat transfer efficiency and operation resistance;
4. Boiler is surrounded by membrane type water-cooled walls on all sides, providing excellent sealing and preventing flue gas leakage, reducing heat loss and improving boiler efficiency.
5. With multiple layers of lightweight insulation cotton overlapped staggeredly, entire coating with heat-resistant paint, it makes heat dissipation loss≤0.15%. Membrane walls around the boiler form a large D-shaped furnace, and furnace volume heat load is ≤500kw, which is more conducive to low-nitrogen emissions with nitrogen oxides less than 30mg/Nm³.
