Prospects of using peat in the regional power engineering

Abstract

Relevance of the work is caused by the need of extensive peat use in terms of huge reserves of peat resources and annual increase in prices for traditional energy. The aim of the research is to examine the main areas of peat use in various industries and to justify optimal method of its application in regional energy sector through the development of recycling schemes using peat gasification capable of supporting object autonomy. The paper considers the existing peat applications synthesized by industry, the most promising of which is the use of peat resources in the regional energy sector. The authors have selected and justified the promising way to use peat in the regional energy-based gasification systems, as well as a scheme of processing peat; have calculated the composition of the product gas for peat samples of the same type and kind, but with different quality characteristics and types of blast. The calculation technique takes into account the stages of drying peat, thermal degradation and peat coke gasification. In the proposed scheme the gasification is carried out in in-line peat generator at high temperature and various kinds of blasting. Electricity and heat obtained from peat resource gasification may be used for technological needs of production lines of peat granules or pellets. The scheme allows providing reliable and independent heating and electricity supply of the systems or enterprises producing different peat products. In this case the processing plant becomes autonomous and non-volatile from centralized energy systems and costly energy sources.
