Reducing the cost and improving the amenity of commercial and large domestic boilerhouse installations
Due to the relatively low capital and routine labour costs associated with oil and gas equipment, the commercial coal market is under pressure to reduce the cost of ancillary equipment and improve boilerhouse amenity. This study is directed towards making improvements in five main areas, coal delivery, recovery from storage bunkers, automatic ash removal, automatic smoke tube cleaning and chimney systems. The following devices are discussed: (i) a flexible spiral screw vehicle unloader; (ii) intermediate bulk storage containers (1.5 tonne capacity bags); (iii) compartmentation of tipper vehicles; (iv) the use of hopper shaped bunker trimming plates with flexible spiral screw conveyors in shallow masonry bunkers; (v) fabricated steel bunkers and a wooden bunker on a steel frame; (vi) a means of minimising risk of fire burning back in underfeed stokers connected into a single flue; (vii) wet and dry ash and grit removal systems; (viii) an automatic smoke tube cleaning and heat transfer enhancing system.
