Environmental and Economic Assessment of Use of Mini-CHP Natural Gas and Biogas-Run

Abstract

The solving of energy conservation and environment pollution reduction issues is assumed the introduction of min-CHP using traditional energy resources (natural gas), as well as renewable energy sources (biofuels). This work is dedicated to economic and environmental analysis from the point of view of the two options of heat and electricity supply of livestock breeding complex for 700 cows. In this work was made economic and environmental analysis of the min-CHP use with gas reciprocating engines with power of 100 kW, which run on biogas and natural gas, taking into account pollution of ambient air and soil by products of combustion. There was found that mini-CHP, which use biogas plants is more expensive than CHP which use natural gas. The efficiency of capital investments by using CHP with biogas plants is nearly doubles that of natural gas. In the case of project lasting up to 12 years is easy use natural gas. For long-term project (more than 13 years) biogas option gas advantage. Besides, biogas plants are effective means for investing money for further extension of agriculture.
