His work focuses on improving efficiency and reducing the complexity of boiler installation processes.

Latest Patents

One of Sagawa's latest patents is a method of building a boiler frame. This new and useful method significantly reduces the need for high load-lifting cranes, thereby improving operational efficiency even in adverse weather conditions. The design incorporates multiple levels of steel supporting posts that are linked together with beams. The 9th floor unit is temporarily fixed to the posts at an intermediate floor position. Suspension rods are then connected to the 8th floor unit and jacked up, while lower floor units are assembled on the ground to form a multi-floor unit. After connecting this multi-floor unit to the 9th floor unit, the temporary fixation is released, allowing for the multi-floor unit to be lifted and permanently fixed to the designated floor positions.

Another significant patent by Sagawa is a method of installing furnace walls of a boiler. This innovative method eliminates the need for dedicated temporary lifting mechanisms and significantly reduces the installation work period. The process involves temporarily suspending two left and right face furnace water wall panels among four panels. The upper portion of the boiler is assembled while it is suspended from a top girder module. The furnace rear wall and front wall are then sequentially hung, and the temporarily suspended panels are moved to their designated positions, connecting them with the upper portion of the boiler.
