Compressor for instrument air. Very accurate instrument to sense values. Sense the signal and shut down some process. If the instrument malfunctions, there is a mess in maintenance.
Build safety systems, instrumentation, valve controls, processing, all combined is called \(\textbf{LPG Gas Train}\). The train may use LPG or CNG as the fuel. Instrumentation valve assembly for instrumentation and control
LPG for fire boiler, same LPG to raise water to 150 or raise steam from 150 to 1100. Design such that total biomass required is so that syngas produced is maximum and we can cut down on LPG.
Packaged Boiler: Water put inside converts partially into steam. Saturated steam contains water as moisture. Unless temp goes past 105\(^0C\) the phase transformation doesn’t take place. This is the Critical Temperature. We take it to 150\(^0C\) or 250\(^0C\). Further complete transformation to superheated steam removes all water
High T. Steam Generator: Input is saturated steam and output is superheated steam. Parameters are feed, temperature: 1150\(^0C\) and flow. Data: Feed is saturated steam and air. Flow- total is 74kg/hr out of which superheated steam is 60kg/hr. Feedgas air at 14kg/hr (based on stoichiometric requirement for combustion). Calculations will be done in next class and quiz. Pressure should also been shown for each of these.
