Technological Basis for the Production of Compounded Boiler Fuel with Improved Operational Properties

Abstract

The article discusses both theoretical and practical studies on increasing the efficiency of boiler fuel use by enhancing its viscosity and temperature properties. This improvement is achieved by blending fuel oil grade 100 with a fraction produced at 250-350°C, obtained by pyrolysis of recycled polymeric raw materials (a 1:1 mixture of LDPE and HDPE) or with used semi-synthetic oil SAE 10W-40 API SG/SJ. It is also suggested to blend boiler fuel following a scheme that involves constant closed-loop pumping of the mixture through a steam heater (40-80°C) and a tank for 30-45 minutes. This process has enabled the production of boiler fuel with superior performance properties, simplifying its use during winter boiler operation, while utilising recycled raw materials to help improve the country’s environmental situation and enhance energy independence.
