The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Boiler Efficiency Improvement - ChemEnggHelp7/10/2020 · Using direct method we can calculate the boiler efficiency using below formula. In this method we do not consider various losses of energy in boiler process. Where, m = steam generation (kg/h), H g = Enthalpy of steam (kcal/kg), H l = Enthalpy of feed water (kcal/kg), W = Coal feed rate (kg/h), GCV = Gross calorific value (kcal/kg)How to improve boiler efficiency by evaluation & …In this method, the efficiency can be obtained by substracting the heat loss fractions from 100. Boiler efficiency = 100 – (L 1 + L 2 + L 3 + L 4 + L 6 + L 7 + L 8 ). Where L 1 = Loss due to dry flue gas. ADVERTISEMENTS: L 2 = Loss due to hydrogen in fuel. L 3 = Loss due to moisture in fuel. L 4 = Loss due to moisture in air.
