| Summary: | This aims of the research is to examine the performance of pressurised
vessel. It is used as biogas holder. Biogas in its is fuel for genzet. Pressurised
vessel is designed with ASME standard and it have internal pressure of 12 bar.
Besides considering outlet pressure of biogas to genzet is 0.025 � 0.1 bar with
pressure adjusting of regulator.
Results of design are dimension of pressurised vessel including shell
diameter of 310 mm, length of 1100 mm, and shell thick of 6 mm. Head of
pressurised vessel vessel uses ellipsoidal shape. Test of perfomance with
compressing air and biogas use reciprocating compressor into pressurised vessel.
The specification of reciprocating compressor has 2 cylinders, bore of 46.7 mm,
single acting with cooling of air. The prime mover is spark ignition engine with
power of 3.5 HP. From this research, compressor is used to compress of air and
gas until absolute pressure of 6 kg/cm2.
Compression is analyzed with process of adiabatic, polytropic, and
isothermal. The compression testing of air is got volumetric eficiency of 82 %. on
709.9 rpm. Air flow from compressor is less when raising of pressure on
pressurised vessel and flowing the highest of 0.18 m3/minutes at pressure of 1kg/cm2. At process of polytropic power is less than process of adiabatic. From
testing is got polytropic power of 0.36 kW and adiabatic power of 0.41 kW. If it is
compared with isothermal approach it gets the most power of 0.328 kW. The
testing uses biogas, compression of pressurised vessel to the absolute pressure of
6 kg/cm2 is got compression characteristic not different with using air. |
