The results of investigations of ways for nitric oxide and carbon monoxide emission reduction, also improvement of heat characteristics of cogeneration units with gas-turbine and piston engines with direction of exhaust from engine to boiler and from boiler-utilizer to active boiler are presented. The investigations were made on the basis of modern computer programs. For module cogeneration units with boiler-utilizer investigations were carried out on special experimental stand with afterburner which was installed between engine and boiler-utilizer. Analysis of obtained results shows high efficiency of proposed ways for improvement of ecological and heat characteristics of cogeneration units.

Key words: cogeneration unit, piston engine, gas-turbine engine, boiler-utilizer, nitric oxide.
