Since established in 1925, we have maintained our steady position as a dedicated boiler manufacturer for 76 years.

　In response to user's needs in 21st century, we now release our new OVS product, a boiler for a middle-sized oil tank vessel. The high-performance and very compact OVS, which has been derived through many improvements in enormous number of delivered boilers, is sure to meet today's needs!

　In the generator tube which we developed, in order to realize high heat exchange performance, generator tubes are arranged between the upper and lower tube plates of the upper drum, and metal stud pins-welded water tubes are arranged in a grid form as a heat exchanger tube.

　In the combustion chamber, water tubes (evaporation tubes), which form a gas-tight water wall, are arranged on the circumference.

　In these arrangements, downcomer tube are arranged at constant intervals.

　Downcomer tubes to which the lower ring header and upper drum can are connected, are provided with diaphragms in the tube to allow for excellent water circulation. As a result, the evaporation side and downcomer sides are separated.

　In the case where two boiler cans are provided, in order to protect an unused boiler, a simmering coil is connected to the downcomer tube for heating the boiler water.
