Hi all, Are there any useful good practice guidelines for the separation distances from public areas for gas turbine power plants in urban areas? Can they be installed adjacent to roadways, for example. Any assistance appreciated.

Hi all, We are planning to build a thermal sludge processing plant. Does anyone have a rule of thumb for Operating and Maintenance costs for industrial thermal plants as a % of capital? There are various figures for thermal power stations, but we would prefer an industrial equivalent. Many...

Hi all, We are looking at chinese turbines as an option for a geothermal development. Small machines, around the 5MW mark. Does anyone have any experience with chinese geothermal turbines? They mostly look like industrial or power steam turbines without much enhancement for geothermal fluids...

Hi, I am restoring a 1923 Climax steam locomotive in New Zealand. The frame/chassis is made up of a pair of channels (one each side of the loco), each fitted with a doubling plate. The chassis is pretty corroded, and we are looking at replacing it. The channel has a standard section, except...

Hi all, We have two 30 year old thermal oil steam generators that we are looking at replacing. One has cracking on the furnace tubes, and we are concerned about the remaining life of the other boiler. We have had the cracks analysed and it appears to be thermal fatigue cracking. The cracks...

Hi, We have a few very small cracks on our steam turbine discs. Does anyone have any experience in assessing these? Thanks.

Hi all, I am interested in pre calculating my PID loop parameters for a pressure control system for a gas pipeline. The pipeline draws methane gas from a landfill up to a blower station. The blower station draws a slight vacuum in the landfill (~ -8kPa) and provides pressurised gas to a flare...

Hi, We are designing a wate tank with level contol on the outlet valves. My question is how do we size the tank to provide a stable system that can handle flow changes allowing the control valves to maintain control. Obviously a small tank will be harder to maintain control. Is there a rule...

Hi all, I'm looking for some design guidance for a natural gas letdown station, ~80 bar to 10bar. It will require a heater. Any tricks would be appreciated.

Hi, Can anyone give some advice on the K valve to use for a 45 y branch on a 760mm CLS pipe and 760 branch. We are looking to use a 45Y versus a 90 Deg branch connection to reduce headloss. Assistance appreciated Chris

We are looking at using pumps as small turbines in an effort to reduce the cost of small turbine installations (30-100kW). Does anyone have any experience with the use of pumps in this application. Thanks,

We are looking at using pumps as small hydro turbines in an effort to reduce the cost of small turbine installations (30-100kW). Does anyone have any experience with the use of pumps in this application. Thanks,

Does anyone have a piping spec covering steam at 61 Barg (900psi) and 442 Deg C (827F) for ANSI B31.1. I'm looking for piping materials, standards, fittings, etc over a range of sizes. Any help appreciated. Regards, Chris

We are replacing a superheater on a sulphuric acid plant. Downstream of the superheater is a 4MW steam turbine. Steam purging is very expensive in an operating plant, and we are considering using chemical cleaning of the tubes post construction. Is the chemical cleaning appropriate for this...
