The more than 2000 steam boilers operating at the thermal power stations of Russia can be divided into three groups, taking into account their operating lifetimes and steam parameters, which determine the efficiency with which they produce electrical energy. Given the expected rise in penalties for harmful discharges into the atmosphere, it is proposed that a way of reducing the nitrogen oxide emissions be chosen for each group that will minimize the expenditure for the owners of thermal electric power plants.

Essentially all the major methods of reducing the emissions of nitrogen oxides from flue gases employed in power generation have been tested on plants in Moscow which burn solid domestic waste for production of heat and electrical energy. Selective noncatalytic reduction techniques for reduction of nitrogen oxides by nitrogen containing substances at high temperatures are to be preferred.

Methods are discussed for reducing emissions of toxic chlorinated dibenzo-dioxins and dibenzo-furans in flue gases at plants which burn solid domestic waste. Results are presented from a study of the efficiency of scrubbing of dioxins by an absorption method at the Cherepovets factory. It is shown that solving the dioxin problem will facilitate an increase in the number of thermal power plants using solid domestic waste being built in other countries.

The successive switching of the phases of lines with control of the induced voltage in the phases through three-phase automatic reclosure makes it possible to avoid switching on interphase short circuits, and in 2/3 of the cases of single phase faults, to avoid switching on short circuits in general. By using this method for testing aerial transmission lines it is also possible to avoid switching the three phases onto a short. Here it is unnecessary to make any significant changes in the functional protective circuits. The proposed method can be used on 330–750 kV aerial transmission lines, as well as on 110–220 kV aerial transmission lines that are equipped with phase controlled breakers and voltage transformers.
