Base model - Values represent a 1,000,000 Btu/hour gas-fired, hot-water boiler operated for 1,500 full-load hours per year with a thermal efficiency of 80%. The performance of this standard unit is based on ASHRAE 90.1-2007. Thermal efficiency (E t) - Represents a boiler's energy output divided by energy input as defined by ANSI Z21.13. A boiler's thermal efficiency rating should be used to

On financial fronts, scales and deposits can aggravate following costs/ losses-1. Higher maintenance costs. 2. High repair costs in case of tube failures. 3. Down times which can affect the production line badly. 4.

Get A QuoteIn general, boiler deposits can cut operating efficiency, produce boiler damage, cause unscheduled boiler outages, and increase cleaning expense. The first anti-scaling preventative measure is to supply good quality demineralised water as make–up feed water. The purer the feed water is, the weaker the driving mechanism to form scale.

Get A QuoteThe flue gas temperature is the temperature of the combustion gases as they exit the boiler. If the flue gas temperature is high, then it is often associated with heat being lost. Flue gas economizers can be installed to recover heat, and enhance the overall boiler efficiency. Radiation and Convection Losses

Get A QuoteScale lowers the thermal conductivity of the surface and promotes poor heat transfer. "The presence of scale is equivalent to having a thin film of insulation across the path of heat transfer from the furnace gases to the boiler water. This heat-insulating material retards heat transfer and causes a loss in boiler efficiency. Stack gas
