Description
MISSION™ OC-TCi is a high quality composite boiler, i.e. a combined oil- and exhaust gas-fired boiler, with a capacity range of up to 6,500 kg/h steam from the oil-fired section and up to 5,000 kg/h from the exhaust gas section. In simultaneous operation the capacity reaches 8,000 kg/h.
The convection part of the oil-fired part and the burner are fully integrated, and standard burners cannot be used for this boiler. The design of the MISSION™ OC-TCi has been significantly optimized to achieve a better self-cleaning effect in the smoke tubes and an improved water level control.
The gas velocity is relatively high compared to our other composite boiler designs, which improves the heat transfer. As a result, the heating surface and weight of the convection part can be reduced significantly. The high gas velocity also makes the boiler very effectively self-cleaning. It is a standardized, pre-assembled boiler plant that is fast and easy to install.
MISSION™ OC-TCi engages less engine floor area and has a lower weight than older designs of composite boilers.
Construction
MISSION™ OC-TCi is a vertical boiler with an exhaust gas section consisting of smoke tubes. The oil-fired part consists of a furnace, steam space, and the convective section, which consists of helix tubes with a turbo cleaning effect, wherein the flue gas flows. The boiler pressure part is manufactured from mild steel able to withstand high temperatures.
Burner
In its standard version, MISSION™ OC-TCi is equipped with a monobloc type pressure atomizing burner, type KBP™. Servicing the burner is easy as a top plate can be opened and the lance can be withdrawn in order to service the nozzle and lance. Access to the oil system and electrical components is possible through two separate covers on the side of the burner. The burner housing is mounted on the boiler front, angled 15 degrees downwards against the furnace bottom. This allows for a longer flame and offers better utilization of the furnace. The flow of the flame becomes optimal, and the result is high performance combustion.
Control system
The reliable and user-friendly microprocessor based MISSION™ CONTROL TOUCH system facilitates the operation and control of the MISSION™ OC-TCi boiler. The intelligent control system provides fully automatic operation of the boiler plant and the pressure jet burner.
The MISSION™ CONTROL TOUCH system includes burner load and sequence controls, water level and safety device, burner motor and fuel heater starter, and starter for the fuel oil pumps.
