The Konutherm marine thermal oil heating systems are commonly applied for heating the ships fuel (HFO-heavy fuel oil) and/or liquid cargo. Our systems are usually also providing the heat for auxiliary systems (HVAC, hot water, etc.) on a ship. In addition of a directly fired heater, significant fuel can be saved by installing a waste heat recovery heater (economiser) in the exhaust gas stack of the main engine(s). These exhaust gas heaters are specially designed to recover maximum energy from the hot flue gases of the ships engine and may provide enough energy for all consumers when well designed. This fuel saving concept is commonly used for the advanced seagoing vessels and supply vessels and is an economic alternative for steam heating systems. A properly designed thermal oil installation can quickly provide significant fuel savings even under severe operating conditions. The thermal oil heating systems from Konutherm are known for their long life, low maintenance and high efficiency.
The Konutherm exhaust gas heat recovery economisers are equipped with an ingenious and robust upstream gas valve system as standard, which ensures that the thermal oil temperature is kept at the desired level. In the event of an emergency the exhaust gas valve opens automatically to bypass which prevents possible overheating/cracking of thermal oil. As a result our systems do not require inefficient dump coolers for protecting the thermal oil in the economiser. And that is another big plus compared to most of low budget thermal oil heating systems. The Konutherm systems do not require to change the thermal oil during their operational lifetime. Thanks to these characteristics, the Konutherm thermal oil heating systems are well-known for their high quality, reliability and low maintenance. Our design is based on maximum heat recovery which results in minimum fuel consumption, where the system efficiency remains high during the complete lifetime of the ship.
