The use of glycerine as motor fuel

Śliwiński Krzysztof, Marek Wojciech

Combustion Engines

2019

R. 58, nr 3

166--172

Glycerine as waste from production accounts for about 10% of the obtained amount of biodiesel. It is a very attractive substance for the industry, however, currently the industry is not able to absorb such a large amount of glycerine produced during the production of fuel. Therefore, one should look for other ways of disposing of glycerol with simultaneous benefit in the form of energy yield or useful products / semi-finished products. The development of glycerine is necessary due to the continuous development of the biofuel market. In the near future, surplus glycerine may pose serious problems in the growth of biodiesel production. The publication presents the results of scientific research on the use of liquid technical glycerine and its processing products in the gasification process, as engine fuel.

The precipitation processes of Manaurite XM superalloy after 2000 hours of aging

Jasiński W., Zawada P.

Archives of Foundry Engineering

2008

Vol. 8, iss. 1 spec.

155--158

This paper presents the results of investigations of microstructure and mechanical properties, in a state of delivery, after 1000 and 2000h of annealing of superalloy samples Manaurite XM taken from a catalytic centrifugal cast pipe. The annealing of the material taken from catalytic pipes at the temperature of 900 °C causes precipitation of intermetallic phases in alloyed austenite matrix. These changes affect the pipes’ mechanical properties.

Nieniszczące metody badań zużycia rur katalitycznych reformerów metanu

Łabanowski J.

Inżynieria i Aparatura Chemiczna

2000

Nr 4-5

14-18

W pracy omówiono mierniki stosowane do oceny zużycia rur katalitycznych pracujących w piecach chemicznych do parowego reformingu metanu. Przedstawiono najczęściej stosowane nieniszczące metody badań zużycia oparte na pomiarze pełzaniowego zwiększenia wymiarów rur, głębokości pęknięć pełzaniowych i ubytku czynnej grubości ścian rur. Słowa kluczowe: rury katalityczne, zużycie pełzaniowe, metody nieniszczące, reformer metanu

The methods of creep damage evaluation of catalytic tubes used in chemical furnaces for steam reforming of methane have been discussed in the paper. The most widely used, non-destructive methods of creep damage evaluation based on measurements of the diametrical growth of the tubes, the reveal of creep cracks and the assessment of the remaining wall thickness have been considered.
