Methods of assessing the economic and technical efficiency of natural gas
replacement with coal-water fuel for heating furnaces of rolling production was proposed.
On the example of continuous furnace of the rolling mill, it was shown that the use of coalwater
fuel at current prices for natural gas and coal can reduce fuel costs by 47 %. The
influence of various factors on the efficiency of coal-water fuel in furnaces of rolling
production was reviewed.
Keywords: natural gas, coal-water fuel, continuous furnace, saving of natural gas
