Mar 15, 2017 · Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes.Learn More
Aug 01, 2021 · The amount of determined waste heat has been compared with the heat generated in the nearest boiler house to identify if all of the waste heat with the techno-economic potential have a heat demand. The results show that 83 GWh or 76% of techno-economic waste heat potential could be adjusted with the generated amount of heat.Learn More

Your boiler is termed Waste Heat Recovery boiler (WHR), and is intended to be supplied as a basic boiler system with pressure and level controls. All applied heat functions and limits are the responsibility of others. All Johnston boilers are built to strict ASME guidelines whether it is Section 1 or Section 4 design.Learn More
Corrosion and erosion of heating elements reduce the heating area. The deposition of dust particles over the heating component at the cold end also reduces the transfer of heat. Low heat conductivity causes a high flue gas temperature at the outlet and low air temperature at the outlet. This results in boiler efficiency reduction[25].Learn More
The primary sources of waste heat in industrial facilities include exhaust gases from fossil fuel-fired furnaces, boilers, and process heating equipment. These types of high-grade waste-heat sources can readily be used to preheat combustion air, boiler feedwater, and process loads. Waste-heat recovery from lower temperature sources, suchLearn More
