HC Deb 16 May 1956 vol 552 cc176-7W
Colonel Lancaster

asked the Chancellor of the Exchequer to list the fuel-saving plant which he proposes should qualify for investment allowance.

6. Mr. H. Macmillan

I have it in mind that when the Finance Bill becomes law, the following plant should be prescribed:

Mechanical firing equipment for solid fuel

  1. (a) Sprinkler, spreader, coking, underfeed, chain-grate, travelling grate and ram type mechanical stokers;
  2. (b) pulverised fuel burners;
  3. (c) solid fuel elevators. conveyors, bunkers, and hoppers, pulverising mills, ash skips, hoists and conveyors, installed as a necessary part of a mechanical stoker or pulverised fuel burning installation.

Oil firing equipment

  1. (a) Fully automatic, semi-automatic and hand controlled oil burners of the following types: pressure jet; high pressure, low pressure 177 and medium pressure air burners; steam atomising burners; rotary cup and vapourising burners;
  2. (b) oil storage tanks, service tanks and tank gauges, service piping, tracer lines, oil cut-off valves, oil filters and oil pumps, installed as a necessary part of an oil burning installation.

Back pressure engines and turbines

  1. (a) Engines or turbines which discharge the whole of their exhaust vapours to process steam or heating systems;
  2. (b) electrical alternators and generators, switchgear. steam driers, steam make-up valves, superheaters and de-superheaters, installed as a necessary part of a back pressure installation.

Waste heat recovery equipment

  1. (a) Flue gas feed water economisers;
  2. (b) waste heat boilers for producing steam or hot water;
  3. (c) heat exchangers and recuperators which recover heat from hot waste gases, vapours or liquids for heating other gases or liquids;
  4. (d) air pre-heaters which recover heat from hot waste gases for heating air for combustion purposes.

Feedwater treatment plant

  • Feedwater treatment plant forming part of a steam boiler installation.

Control equipment

  1. (a) Devices for automatically controlling the production and distribution of heat, namely, automatic combustion regulators, automatic dampers, thermostats, pressure switches, time switches, boiler water level controls, gas pressure governors;
  2. (b) indicating and recording instruments affixed to boiler or furnace installations, namely. CO2, indicators or recorders, draught gauges, flue gas temperature pyrometers, steam meters, boiler feed water meters, smoke density alarms, indicators and recorders;
  3. (c) devices for assisting the control of combustion in boilers and furnaces, namely, forced draught fans and induced draught fans, smoke eliminating doors and fittings of the types so far developed by the Fuel Research Station.
