SZL Water Tube Quickly Installed (Assembled) Steam Boiler

Product Description

SZL water tube quickly installed (assembled) boiler has 2 vertical steam drums, and the innovative horizontal cyclone-fired combustion chamber, which could effectively enhance the thermal efficiency and reduce the flue gas emission concentration. The flue gas emission concentration is lower than 100 mm/nm3, the flue gas blackness is lower than Ringelmann level 1, which enables the boiler to be used in the first-class environment protected area. The boiler installs one cast iron economizer at its afterbody, the fire-gate applies the chamber-segregated ventilation structure, which is easy to adjust. The separate-layer coal supply device could be chosen according to the customer requirement. Advantages of such boiler are: Strong power, high thermal efficiency, 110% override capability, compactly designed, small floor area. Customers appreciate its safely operated, investment conserved, and broadly fuel adapted capability most.

SZL series steam boiler specification and boiler auxiliaries (as table).

Remarks:
1. The parameter in the upper sheet is only for your reference, we will not inform customer the varied size and dimension due to the design and installation;
2. The coal consumption is calculated according to the coal in bulk heat rate 6000 kcal/kg;
3. The boiler exterior size is in accordance with the design drawing.
