thread124-198506 I am responsible for designing a spray water system for a desuperheater that utilises steam condensate. We are currently using boiler feed water but it is causing caustic embrittlement on the steam piping, hence the change. I am sizing a pump and control valve for the new...

rmw, Firstly, my apologies for the double post - I am a chemical engineer and naturally posted it there first. I then posted it here because I wasn't sure if mechanical engineers like yourself would see it. But sorry for any trouble caused. The company I work for is Sappi. Can I assume that...

dcasto, I appreciate your point, but currently my country (South Africa) is going through a power supply crisis and is forcing industries to reduce electricity usage/dependance by 10%. Although the energy can be used to heat something, an electricity reducing/generating initative carries more...

rmw, Thank you for the information - it has been a real eye opener! The paper mill where I work is in Gauteng, South Africa. Are you able to name any of the paper mills that implement this technology? The company I work for has paper mills around the world so perhaps I could get assistance...

MJCronin, Inlet P = 1300kPa (gauge) Outlet P = 385kPa (gauge) Ave q = 20 tph Hours/yr = 8400 DCasto, We currently have PRV's in the steam line where this energy is lost.

Sacem1, Our boilers produce steam for the entire paper mill, which has many sub-sections eg. Pulping plant, belaching plant, paper machines, liquor recovery etc. Each subsection use steam at different pressures (and temperatures). That is why we distribute steam at a constant 15bar to all...

Hi, My company has recently discovered the potential benefits of replacing pressure reducing valves (PRV) on the steam line with steam turbo-generators. We approached a supplier to assess the potential for generating electricity in our steam system. With the information we gave them, they...

Hi, I am planning to install a heat exchanger on an existing water line. The water is pumped from a tank through an anion resin unit and then to a another tank. The heat exchanger will be installed after the resin unit. I want to install an in-line booster pump on the water line to accomadate...
