New Projects Section
7.17. Various alterations have been made to improve the operation of the Kennedy Town Incinerator Plant. These include the reconstruction of the induced draught fan plinths which were found to be insufficiently rigid. A modification was also made to the draughting of one of the furnaces whereby hot gases are drawn down through the refuse in the drying zone. By this means the excess moisture in the refuse is drawn off before a blanket of steam can form to hamper combustion. This arrangement is now being extended to the other furnaces and great improvements in the burning rate are expected. Other investigations and modifications to improve the hydraulic operating mechanisms of the plant and the cranes in the reception section were in progress.
7.18. The erection of the Lai Chi Kok plant is almost complete and modifications to it are being incorporated on a continuing basis, following the improvements achieved at Kennedy Town.
7.19. Four small incinerators for the Medical Department were installed in various hospitals.
7.20. For the new abattoirs a 30,000-gallon fuel tank was installed at Kennedy Town and a 15,000-gallon one at Cheung Sha Wan, while a cross connection of steam mains was made between the Abattoir and the Incinerator Plant at Kennedy Town.
7.21. The 600,000 cu. ft./minute Ventilating Plant for the Lion Rock Tunnel was installed and brought into use early in November 1967 and has proved effective in service.
7.22. At Waglan Island a funicular trolley way was designed and was in process of erection at the end of the year. One 300 and one 500-ton winch together with dockside cranes were also in course of installation at the new Yau Ma Tei Slipway for the Marine Department.
7.23. At Queen Mary Hospital a scheme is in hand for a new Steam Distribution System in the original building. Phase I was completed in December while Phase II, including replacement of the 30-year old boilers, was well under way. The Steam Supply System for the new
