COTES Engineering company performed pilot combustion of the off-grade coal for the needs of OOO Vorkutinskiye CHP plants (affiliated with PAO T-PLUS). COTES professionals performed combustion of highly moist gas fat meager coal of the rice/culm grade in 9 CHP-2 plant boilers. Tests were carried out in three types of boilers: TP-170-1, BKZ-160-100, BKZ-22-100-4. As a result, COTES engineers issued recommendations as to combustion of the off-grade coal in existing boilers, as well as proposed engineering solutions for reliable and cost-efficient operation by using such type coals, with making the cost estimate of relevant works on a turn-key basis.
