MGGH System Design
Tube bundles configured in the Mitsubishi Gas Gas Heater (MGGH) are divided according to the optimum size and weight requirements for the manufacture, transportation and installation. This enables easy maintenance by individual dismantlement and installation. Also, heat transfer tubes, in the shape of trombone, ensure a compact structure. The flexibility in design means that either horizontal or vertical flue gas flow can be selected depending on site specific factors.
