Furnace Technology - Section 1 (4)

Ceramic coating material for furnace refractory, which increases its emissivity and thus the radiation heat transfer rate in the furnace, comprises of

Temperature of a furnace fired with low calorific value fuel gas (i.e. lean gas) can be increased by

Higher furnace temperature can not be achieved by use of a lean fuel gas in the furnace by

The thermal efficiency of a steel slab reheating furnace (walking beam type) may be about __________ percent.

Tunnel kilns are usually used for

Fuel used in B.F. stove is

In producer gas making furnace, steam is added along with air to mainly control the

Thermal efficiency of a limestone calcination rotary kiln may be around __________ percent.
