The Camberley plant is a large commercial laundry part of the CLEAN group of laundries. This plant processes up to one million pieces of linen per week on a two shift/7 day per week operation. For Clean Camberly, the use of and RO plant and injection of amine is very successful. The boilers have stayed…
It’s quite common in boilers with base-exchange water softeners, the effects are worsened by having hard water and/or high make-up rates. If you have a base-exchange softener the scale forming calcium is taken out but the carbonate remains, this doesn’t harm the boiler but instead breaks down to form CO2. This CO2 leaves the…
Fully manned A competent boiler operator in the boilerhouse whilst the boilers are operating. Local manning A competent boiler operator on site whilst the boilers are operating. Must be within earshot of alarms and able to attend within 7 minutes. Unmanned (level 1) A competent boiler operator must attend the boilers on a daily basis….
A personal assessment by Kenneth Fergusson, Honorary Vice President of the Combustion Engineering Association. In London, 23rd January 2017 dawned windless, foggy and frosty. 100 flights were cancelled at Heathrow. The BBC reported that the conditions were widespread across the country. Looking at the weather map, I remembered an article written back in November 2003, when…
The purpose of boiler control is to achieve safe operation, reliability and optimised performance with respect to load change response, fuel cost and emissions. In most control applications, repeatability or measurement is more important than absolute accuracy. Accuracy can be adjusted for software, but erratic readings cannot. Drum level is critical for safety and reliability….
Providing solutions to complex Burner Management System (BMS)applications requires a combination of process knowledge, regulatory awareness, robust components, and an intuitive interface all applied with industry experience to ensure that life, equipment, and revenue are well-protected. A BMS is truly the last line of defense in preventing the catastrophic failure of a boiler, fired heater or…
Industrial power and utility operations are amongst the biggest users of fuel, and greatest generators of emissions. With escalating fuel costs and challenging environmental regulations, it is important that these facilities operate at their best. Efficiency must be maximised across the entire operation, waste and low-cost fuels need to be leveraged to the highest degree…
Steam is a critical part of many process manufacturing processes and the energy to produce it can be a significant source of operational costs. Jim Cahill recently caught up with process automation hall-of-fame member Greg McMillan and Emerson’s Scott Pettigrew at the Emerson Exchange conference in Austin. Greg and Stan Weiner had recently interviewed Scott in a ControlGlobal.com article, Boilers as fast as can…
Environmental sustainability has never been so important and this pressure is leading many plant engineers to explore ways they can reduce boiler house energy consumption. A common idea is to reduce boiler pressure to save energy, but does it work? Chris Coleman, Marketing Product Manager at Spirax Sarco, explains how steam system pressure and fuel…
What Are the Implications of De-rating Boiler Pressure Below that of Boiler Design Pressure Is it appropriate on your plant to reduce the boiler operating pressure with a view to saving money on fuel costs, when you consider both the effects on the plant and equipment and the associated risks of making the necessary changes?…
