Working with SGT-700, i recently observed this strange phenomenon of the GTG Air Filter Dp falling (0.51 to 0.42kPa) after there was slight drizzle. Falling Dp can be caused by either A) HP side falling: Ruled out - 04 Trasnmitters monitoring the Dp showed same behaviour B) LP side Rising...

I am working with SGT 700. I came across a peculiar thing wkile looking at the HMI. The Dp across filter set is 0.55kPa, further the Dp across the Compressor inlet plenum (used to calculate air mass flow) is 9.3kPa and finally at compressor inlet the ABSOLUTE Pressure is 95kPa. Calculating...

I am working with SGT 700. The air intake has two stages of filters, the jet pulse canister filters and the HEPA stage. The jet pulse canister filter is a two piece module. I wonder why couldn't they be use a single piece canister? The air flow is from right to left <-------

We have an HRSG as a part of GTG-HRSG package. It has two burner stages. The gas fed to it comes in at fixed Temperature and pressure. It then bifurcates for each stage. Each stage pipeline has same Control Valves, Flowmeters and other instrument fittings. The gas to first stage has to be...

Above is a part of the HMI graphic for SGT700, Air intake system.It is obvious the Dp across individual air filters is there as a reflection of the health of the filter(i.e. Choking/resistance to air flow). But what intrigues me is the Dp Across the two filter sets (middle one 0.06Pa), is...

I wish to understand why does the gas turbine need pilot burner as well as the main burner. I am working with SGT700, the burner fuel supply is split into Main gas and Pilot gas. The main gas get mixed with the compressed air and burns inside the burner. The pilot gas is supplied at the tip and...

SGT 700 has a simple arrangement for ventilation of the GTG enclosure, a fan sucks in air from the atmosphere through a filter, pushes into the enclosure from one end and the air leaves the enclosure on other end. The Dp.filter has no tripping setting but only shows an alarm after the Dp...
