Energy and economic effects of the steam-and-gas heat-and-power plant cooperating with the low-exergy heating system
Technical conditions for the application of a low-exergy (low temperature) heating system of buildings have been discussed. Cumulative economy of the chemical energy expected after introducing the steam-and-gas HP plant fed with natural gas has been analyzed. Approximate determination of the production cost of the useful heat in the considered system has been performed. The influence of the sell price or avoided purchase cost of the electricity has been investigated.
