Nominal evaporation capacity: 35 t/h
Nominal operating pressure: 0.7 MPa – 2.5 MPa

Features:
1. This single-drum water-tube boiler consists of a boiler unit at the top and a chain-grate stoker at the bottom; it can be assembled at the factory and shipped as a complete unit.
2. The boiler body is arranged vertically with a single drum. The drum and the water-wall tubes on both sides form the radiant heating surface of the furnace, while the convective heating surface consists of water tubes and tube bundles on both sides.
3. A spiral flue tube located within the drum serves as a convective heating surface, and the tube sheet utilizes a non-extensible, arc-shaped design characterized by low stress.
4. The boiler is equipped with a coal-fired chain-grate stoker.
