Opportunity of external combustion engines usage in forestry complex

Abstract

Considered problem of forest industry enterprises energy supply. Are taking in account following: energy communications remoteness, high cost of accessing to energy networks if they are near to logging site. Most of remoteness logging sites are energy supplied by diesel power plants. This situation leads to problems: high price for 1 kW, expenses fuel transportation. Observed possibility of Stirling engine usage in forest industry. First of all – electric generator based on Stirling engine, which allow to use biofuel. Considered possible schemes of Stirling engine usage. Co-generation scheme – secondary heat utilization. Direct generation with different biofuel usage. Defined the range of required Stirling power stations powers for forest industry. Was analyzed Stirling engine kinematic schemes: α, β and γ-type. Are defined more suitable type to use in logging sites - α-type. Air was selected like working body. Were analyzed mail difficulties of Stirling engine construction. The absence of calculation technique and experimental experience are show necessarily of construction parameters and heat-mass transfer analysis. Further issues of investigations were defined: complex and multiparameter numeric modeling of Stirling engine operational process with different power ranges and optimal construction parameters finding out for successful introduction of Stirling engine in forest industry were defined.
