Rapid determination of total sulfur content in - NCSU
Reduction efficiency can be used to regulate the combustion process of the boiler (i.e., combustion temperature, air supply, and mirabilite dosage). The following formula is commonly used to calculate the reduction efficiency of green liquor in the factory (Biermann 1996). Reduction efficiency (%) =Na 2 S/(Na 2 S + Na 2 SO 4) * 100 (1)

Introduction to Condensate Recovery - Spirax Sarco
The average boiler steaming rate is 15000 kg/h, and the plant operates for 8000 h/year. The fuel used is gas on a firm tariff of £0.011/ kWh, and the boiler efficiency is estimated as 80%. Make-up water temperature is 10°C and insulated condensate return lines ensure that condensate will arrive back at the boiler house at 95°C.

Boiler Ratings Explained - Heating Help
Jun 18, 2014 · For instance, if a boiler has an Input of 200,000 BTUH and a Gross Output of 160,000 BTUH, that boiler would be running at 80% combustion efficiency. It's not hard to figure this out. Just divide the big number into the little number and then multiply the result by 100 to get a percentage. And this brings us to Net Output.

Jul 05, 2009 · Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.
