The circumstances of solid fuel burning domestic appliances in England, West Germany and other European countries were surveyed.
The solid fuels consumed for domestic heating are about 10% of the energy in West Germany and about 20% in England.
The solid fuels of those countries are anthracite, bituminous coal and manufactured smokeless fuels. They are less in ash content and are screened at more narrow sizes than Hokkaido house coal.
The standards of the solid fuel burning roomheaters in both countries have been established for the performances and the methods of testing since 20 years . The European stoves have the following performances and constructions.
(1) They are larger and heavier, and have much fuel capacity and higher heating efficiency than Japanese stoves burning solid fuels.
(2) The combustion air is controled by thermostatt working mechanically by boiler water or the other parts of stoves.
(3) They maintain an effective seal of both the door opening and the ash pit opening.
(4) Most of them are covered by ceramic tile, polished soap stone, decorated cast iron, etc., and the visual appearance is most attractive.
In England, some new types of appliances have been developed by colabolation of NCB CRE and appliance makers, which are based on the down draft burning principle and are capable to reduce smoke emissions to the levels 'required by the Clean Air ACT.
