K/KD

Composite Boiler

Capacity: Oil fired part up to 5000 kg/h / Exhaust gas

part up to 3500 kg/h; Design pressure: 1,8 MPa

Design Features:

The K/KD boiler is a composite exhaust gas and oil fired smoke

tube boiler. The furnace of the oil fired part is designed as a

cylindrical vessel with dished ends which is completely water

cooled and equipped with bottom refractory.

The heat transfer in the oil fired part is performed via a number

of special pin tube evaporation elements, each with the heat

transfer capacity of several plain tubes, keeping the oil fired

part as compact as possible. Considering the inevitable amount

of residues in the exhaust gas of the usual HFO fired main

engine, the exhaust gas fired part is designed with straight

smoke tubes which are easy to clean and maintain.

The special spherical shape of the furnace cover protects this

part of the boiler against partial overheating because it pevents

residues in the boiler water from accumulating on the surface.
