AUTOMATIC CONTROL OF THE COMBUSTION PROCESS FOR A PULVERIZED-COAL FIRED BOILER, ENSURING THE SUPPRESSION OF EFFLUENTS OF MITROGEN OXIDES

New representations about control of a furnace process with the stepwise combustion of fuel have been obtained in the paper. The automatic control system for the combustion of a pulverized-coal fired boiler has been created on their base. The methodology for the adjustment of a multiconnected automatic control system applicationly to the furnace process considered has been suggested. Variants of schemes for the NO*00x content control in flue gases have been developed as well as methodologies of their adjustment under industrial conditions. Technical solutions and recommendations have been introduced into operation. Effluents of NO*00x have been reduced for 25 - 30% due to the maintenance of the given dependence of NO*00x at the load modificationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
