Analyses of three stages of TP-87 boiler reconstruction at Zapadno-Sibirskaya CHPP are resulted. The purposes of reconstruction consisted in decrease in NOx emissions and increase in reliability and profitability of the boiler operation at combustion of kuznetsky coal of GR and GROK ranks. Technical solutions for stag-tap boilers of TP-87 type on increase in operational reliability and decrease in specific NОх emissions to the standard level are offered.
