Q. What temperature do I need to get the boiler in order to start blasting operations? |
|
|
|
A. Firebox Cleaning Binary Applications: We like to arrive on site once boiler gas out temperature reaches 300 degrees F. At this time the erection of barricades are performed in addition with any other preliminary set up. Also at this time pre-job safety meetings are conducted along with any other coordination meetings with other contractors that may be working onsite. Once boiler temperature is reduced to 175 degrees ambient air temperature blasting operations will commence. Convection Areas Primacord Applications: Once boiler temperature will permit entry, blasting can commence in the backpass areas. Depending on slag build up in the areas to be cleaned, it usually requires 12 hours to cool the backpass areas to allow the installation of explosive primacord. |

|
Q. What is your response time in an emergency or forced outage situation? |
|
|
A. Explosive Professionals, Inc. prides itself in being able to respond to any customer in the continental United States in a six to eight hour window. Normally this is more that adequate due to the time that is involved with the boiler cool down.. |
|
|
Q. Is the size of the boiler a critical factor in determining the visibility for explosive cleaning? |
|
|
A. Over the years, it has been our good fortune and experience to work in various boiler types and sizes. These boilers range from the 50 MW Foster Wheeler's to the 1300 MWB & W's. What we have found to be critical is not primarily the size of a boiler, but the access to the slag location, density of the slag, window of opportunity, and the customer's definition of clean. |
|
|
Q. In what other areas do you offer explosive cleaning? |
|
|
A. In conjunction with firebox cleaning, we also offer a variety of other applications. These areas include the burners and platens, horizontal back pass and economizers, bottom ash and economizer hoppers, throat clinkers, scrubbers, coal silos and frozen coal piles. |
|
|
Q. Have you ever had an insurance claim associated with boiler cleaning? |
|
|
|
|
A. Since the opening of Explosive Professionals, Inc. in 1995 there has never been an insurance claim. |
