After measuring and calculation, the recommended energy saving solutions for the coal fired boiler are:
-Insulation for whole boiler wall, boiler outlet channel, economizer and steam drum. Minimization of heat transfer to ambient and cool air entering into furnace;
- Insulation for condensate tank and pipeline;
- Improvement or replace of new damper of exhaust fan. Improvement, repairing of air damper to be easier for adjustment of burning mode;
- Installation of ash cyclone on chimney, to bring the incompleted burning fuel back to furnace to minimize mechanical loss;
- Installation of measuring meters, mornitoring of technical and economic criteria for boiler (feed water meter, coal balance, consumped power meter of air fan and exhaust fan, thermometer…);
- Testing to find out the best burning modes for boiler to be appropriate with actual production and to achieve the highest efficiency of boiler.
