Abstract: This paper presents the calculated data on the emissions into the environment from the low-waste energotechnological solid heat carrier units (SHCUs) working with oil shales. A comparison of this technology with direct oil shale combustion at a power plant was carried out using the example of an Estonian power plant. The energotechnological plant (ETP) including two units SHCU-3000 with an oil shale capacity of 3000 t/day (~ 1mln t/year) each was created, with the boiler on shale oil and a power unit of 200 MW. It is shown that total emissions are lower in the case of an ETP operation of a thermal power plant together with a power unit than in the case of the direct combustion of oil shale. The ash from the ETP and the pyrogenetic water can be used in industry and agriculture.

Keywords: eEnergotechnological plant; solid heat carrier unit; low-waste technology; atmospheric emissions; water discharges.
