Read MoreRiley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.
Read MoreThe coal-water slurry (CWS) is a potential new form of fuel for application in power boilers and industrial furnaces. The single suspended coal-water slurry droplets have been burned in hot gas streams to reveal their basic nature of evaporation and heating processes. Temperature measurement and microscopic observation are performed.
Read MoreDec 19, 2014 · The rotten egg smell is also common in both boilers and water heaters when bacteria begins to grow. It's not dangerous in those cases, but it is unpleasant. It results from the growth of anaerobic bacteria in the magnesium and aluminum parts of the boiler. The anodes may need to be replaced to get rid of the bacteria and egg smell.
