The Partial Replacement of Diesel Fuel in Hot Water Boiler with Syngas Obtained by Thermal Conversion of Wood Waste

Abstract

This paper presents experimental results on the use of syngas produced from waste wood by two-stage pyrolytic conversion method, in the implementation of heating system on a basis of hot water boiler. The method of two-stage pyrolytic biomass processing, combining the waste wood pyrolysis, and subsequent heterogeneous cracking of volatile pyrolysis products in charcoal bed, provides a high degree of energy conversion of raw material into syngas with a lower calorific value of 10-11 MJ/m 3 . The possibility of partial replacement of diesel fuel in hot water boiler with syngas was shown.

Investigation of the influence of the microcapillary structure of natural skins on relative humidity in vacuum-sorption humidification

“…The time of maximum filling of the microcapillary with moisture calculated according to the formula (9,10) will be 480s [10] (the relative humidity of the leather samples is 36,8% and this value can be recommended with intensified hygrothermal treatment of natural skins in the corresponding equipment [17][18][19][20].…”
