LIGHTING EQUIPMENT AND HEATING FUEL

Abstract This paper presents the results of a research on the influence of potato pulp content in a mixture with oat bran on the power demand of the pelletization process and on the quality of the produced pellets, in the context of use thereof as a heating fuel. The tests of the densification of the pulp and bran mixture were carried out on a work stand whose main element was a P-300 pellet mill with the ‘flat matrix-densification rolls’ system. 24 h after the pellets left the working system, their kinetic durability was established with the use of a Holmen tester. The research results obtained in this way allowed concluding that increasing the potato pulp content in a mixture with oat bran from 15 to 20% caused a reduction of the power demand of the pellet mill. It was also established that as the pulp content in a mixture with oat bran increases from 15 to 25%, the value of the kinetic durability of the pellets determined using Holmen and Pfost methods decreases.

Pyrolytic Oil

Due to its high total sulphur content and other unfavourable properties, pyrolytic oil obtained as a result of tyres pyrolysis is not suitable for use as motor or heating fuel. Therefore, pyrolytic oil was hydrorefined. Hydrorefined oil was used as a component of light heating oil. A composition was prepared from 30 wt % hydrorefinate with 70 wt % Ekoterm Plus (a commercial oil). Unfortunately, the flash point temperature of the hydrorefinate was too low, and did not allow fuel compliant with the Polish standard PN-C-96024:2011 for L1 light heating oil to be obtained. Therefore, the fraction with boiling point below 180 °C was removed from the hydrorefinate. The residue, with a flash point of 74 °C and a sulphur content of 0.143 wt %, was mixed with Ekoterm Plus and fuels with a hydrorefinate fraction content of 30 and 50 wt % were prepared. The composition containing 30 wt % met the requirements for L1 oil in the whole range of tested parameters. Total sulphur content was 0.092 wt %, specific weight was 856 kg/m3 and closed cup flash point was 64 °C. However, the composition containing 50 wt % hydrorefinate did not meet the requirements regarding sulphur content and specific weight. Sulphur content, specific gravity, and flash point are the parameters limiting the possibility of using hydrorefined pyrolytic oil for composing light heating oils compliant with the mentioned standard.

ABSTRACT The use of a continuous-flow vortex separator as a component of an oil spill clean-up system was investigated. Tangential injection of the oil-water mixture into the vortex tube produces buoyant forces which accelerate the lighter oil to the vortex axis. The cleansed water and the core containing the oil are exhausted through exit ports in opposite end walls of the vortex tube. The cleansed water would be returned to the sea and the core flow containing the oil would be stored. Tests of laboratory-scale model vortex separators were made using oil-water mixtures having inlet oil-to-total-flow ratios between 0.002 and 0.3 and for a variety of geometric and flow conditions. The tests were made using four types of oil (napthene-base crude, paraffin-base crude, diesel and No. 6 heating fuel) having viscosities between 3 and 4250 cps (measured at 75 F) and specific gravities between 0.83 and 0.97. The results showed that separator performance may be optimized by proper control of the oil exhaust flow. Under optimum conditions, approximately 90 percent of the injected oil was separated and captured, and the captured flow contained approximately 90 percent oil. Studies were also made to determine the sizes and weights of components for full-scale vortex separators, including the necessary pumps and prime movers.

Heating Fuel

From the beginning of construction in the territory of Latvia there was an important issue that affected any house. How to get heat? As the territory of Latvia was always rich in forests, the answer was obvious - with firewood. This heating variant is also topical today. However, with the development of heating and the rhythm of human life, many classic heating, with wood, is not enough. Consequently, the author looks at the types of heating in Latvia's households and their development. As well as the consumption of wood fuel and its development trends. Wood specialty products, such as pellets, are nowadays a popular fuel. This article will be useful for those who are considering upgrading or converting a heating system that is going to build a new building, as well as producers of fuel and heating systems.
