A large number of companies have switched their boiler fuels to use white coal instead of fossil fuels.

Combustion studies have been undertaken and it appears to be well-suited as a commercial boiler fuel.

In some regions it is used as boiler fuel as a means of reducing energy costs, for which it is quite suitable.

And the mileage, about 8 to 12 miles per gallon of boiler fuel, offers no advantage compared with internal combustion engines.

Gasoline was added in 1981, crude oil in 1983, propane in 1987, residual oil, or boiler fuel, in 1989, and natural gas this spring.

A number of companies in India have switched from furnace oil to biomass briquettes to save costs on boiler fuels.

A number of units in Maharashtra (India) are also using biomass briquettes as boiler fuel.

Lanxess India and a few other large companies are supposedly using biomass briquettes for earning Carbon Credits by switching their boiler fuel.

Some of the slabs and edgings can be used as boiler fuel; some can be sold locally as firewood.

Amoco will take the oil to refineries and reprocess it, for use as lubricating oil or boiler fuel.
