Using Explosives for Boiler Deslagging

COAL POWER magazine :: Operations & Maintenance >> 
This unconventional technique for removing slag from solid fuel-fired boilers, used for more than two decades, has exploded in popularity. But the risks are very real, and not all blasters are created equal....

NERC: Loss of Reactive Power, Voltage Instability Likely Outcome from Geomagnetic Disturbance Effects

COAL POWER magazine :: Operations & Maintenance >> 
A new report released in early March by the North American Electric Reliability Corp. (NERC) found that loss of reactive power was the most likely outcome from a severe solar storm that was centered over North America. Significant losses of reactive power could lead to voltage instability, and, if not identified and managed appropriately, power system voltage collapse could occur, the report concludes....

Preventing and Mitigating Oil Fires in Power Plants

COAL POWER magazine :: Operations & Maintenance >> 
It has been said that a picture is worth a thousand words. However, photos of the conflagrations that have resulted from ignition of minor lube oil leaks on a typical steam turbine room floor will leave you speechless. Full-scale physical simulations of oil fires by the insurance company FM Global leave no doubt that power plant fire prevention and mitigation is a judicious blend of art and science....

Wet Booster Fans Optimize Power Station Performance with FGD and Wet Stack

COAL POWER magazine :: Operations & Maintenance >> 
A Romanian lignite-fired power station wanted to minimize the operating cost of the flue gas desulfurization (FGD) system by placing the booster fans in the "wet position," between the wet FGD scrubber and the wet stack, where they would consume significantly less power. A number of combined environmental effects must be considered in this design....

Improved Performance from Priority-Based Intelligent Sootblower Systems

COAL POWER magazine :: Operations & Maintenance >> 
When sootblower operation frequency is too high, a plant risks losing power generation from tube leaks; but when sootblower frequency is too low, there is a risk of boiler pluggage. Intelligent sootblowing finds the right balance between tube erosion and plant economic operation....

Pulverizers 101: Part III

COAL POWER magazine :: Operations & Maintenance >> 
Pulverizers prepare raw fuel for burning by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. Part I of this three-part report examined the essentials of pulverizer design and performance; Part II discussed the importance of fuel fineness. This final article discusses the importance of air and fuel measurement....

Micronics – Lodge Cottrell - Application Note Approved Release

Lodge Cottrell use Micronics PF330 Portable clamp-on Flow Meter to substantially reduce commissioning time and fixed installation costs on large scale pollution control plant for coal fired boilers.

 

Lodge Cottrell is a world-leading supplier of large-scale industrial air pollution control equipment. On a project carried out during 2010 they had a requirement to process the ash extracted from their boiler flue gas treatment system by mixing this with water to form slurry suitable for disposal.

 

COCHRAN PROVIDE TOTAL TURNKEY INSTALLATION FOR TWO 10210KG/HR STEAM BOILERS

Cochran Ltd have recently handed over complete turnkey installation of two high efficiency Thermax steam package boilers to Billerud Beetham, Milnthorpe, Cumbria.

 

Billerud Beetham who specialise in producing different types of packaging and paper for industrial use including grease-resistant paper for fast-food industry and paper that can be sterilised for medical applications were looking into replacing three 40 year old boilers with two new steam boilers capable of integrating with an additional Cochran Thermax and Ruston Thermax boiler choose Cochran Ltd to provide total turnkey installation.

 

Spirax Sarco opens new state-of-the-art Steam Technology Centre

Spirax Sarco shows its continued commitment to world-class training with the opening of its UK Steam Technology Centre. The centre is the only training facility in the UK to offer a fully-operational steam system with SCADA control. This enables it to enhance the quality of training across Spirax Sarco’s array of steam engineering courses, as well as supporting live technology demonstrations.

 

The revamped centre offers a variety of training courses to help steam system operators address key issues, such as improving energy efficiency and carbon emissions, reducing downtime and operating costs and ensuring safe operation.

 

Is this the oldest Operational Boiler? We think it could be...

David Young, Cochran General Manager, recently took a call from a boiler insurance inspector based in South Africa. He was trying to trace design and manufacturing records for two vertical Cochran boilers still installed and operating in Calitzdorp, South Africa.

Impressively we were able to supply the required records for the boilers built in 1939 and 1945 and more impressively the boilers passed their inspection and continue to deliver.

Cochran Supply New Steam Boiler for Spirax Sarco's Steam Technology Centre

We have recently supplied and commissioned a new Borderer reverse flame steam boiler for Spirax Sarco’s Training and Steam Technology Centre in Cheltenham.

When Spirax Sarco were considering to extensively refurbish their training Centre they selected the Borderer steam boiler manufactured in Annan, Dumfries & Galloway by Cochran Ltd, the UK’s  leading manufacturer of industrial steam and hot waters boilers.
