End Use of Fuel Consumption The Manufacturing Energy Consumption Survey (MECS) collects fuel consumption by end use for six major energy sources – electricity, natural gas, coal, LPG, diesel/distillate, and residual fuel oil. Coke, an energy source used for fuel in a blast furnace, is not included as one of the six major energy sources when collecting for end use in the MECS.

Since coal is an energy source with abundant and ubiquitous reserves, the increasing demand for power generation by coalfired units is expected to continue in the coming years. Of all the recoverable coal reserves, approximately 50% are lowrank coals such as lignite and subbituminous coal.
A detection low level of carbon monoxide produced by combustion within the mill is a proven method of detection of coal mill fires. Early detection of fires in coal pulverizing mills is essential to avoid catastrophic damage to plant and to avert the threat of injury to personnel.
COAL HANDLING Protecting the coal mill by monitoring CO and O 2 CO and O 2 measurement in the coal mill is important for early warning of a smoldering fire and/or a leak in the inerting system. The MKAS analyzer system equipped with an explosionprotected sampling probe is the ideal solution for this. The MKAS can be configured to sequentially
