HC Deb 26 January 1970 vol 794 cc232-3W
48. Mr. Eadie

asked the Minister of Technology what progress is being made in the production of fire appliances that burn smoky coal smokelessly; and what aid is being given by his Department to their production.

Mr. Alan Williams

Market tests of the appliance of the room heater type developed by the National Coal Board are still in progress in the Midlands, and development work is continuing on other versions using the same combustion principles. The work is being undertaken in conjunction with manufacturing firms and no question of aid by my Department has arisen.
