Overview: The document provides technical details about the PARAT MCS Combined Smoke Tube / Exhaust Gas Boiler, designed by Parat Halvorsen AS. This boiler integrates both oil-fired and exhaust gas sections, offering a cost-effective and efficient steam system for ships.
Design and Construction: The boiler features a vertical design with smoke tubes and steam evaporation occurring at the upper section. It is constructed according to approved drawings by all classification societies and meets class requirements. The combination of oil-fired and exhaust gas sections simplifies installation and maintenance, reducing costs over the ship's lifetime.
Functionality: The boiler operates on a principle of common water and steam space with separate sections for oil firing and exhaust gas. It can accommodate multiple engines with separate exhaust gas sections. The automatic mode prioritizes the exhaust gas section as the main heating source, with the oil burner maintaining pressure if needed. The control system supports unmanned engine room operation, utilizing electronic controllers and electric/pneumatic actuators.
Control and Connectivity: The boiler control panel is operated via a local touch screen, and the PLC can connect to the main control system through standard communication protocols like ethernet, profibus, or modbus.
Certifications and Features: The boiler is certified under NS-EN ISO 9001 and approved by various classification societies such as DNV, LRS, BV, and ABS. It offers a compact, two-in-one solution with options for vertical or horizontal design, easy maintenance, and a smoke tube type. It has a capacity of 3.5 t/h for exhaust gas and 5 t/h for the smoke tube boiler. Additionally, it is available with an ASME S-stamp and can be equipped with oil, gas, or dual fire burners.
