combustion process in a front wall pulverized coal fired utility boiler of 350 MW with 24 swirl burners installed at the furnace front wall. Five different cases with 100, 95, 85, 70 and 50% boiler full load were simulated. Comparisons were addressed, with good agreement between predicted and measured results in the boiler for all but one case thus validating the models and the algorithm

Coal fired power plants can achieve the highest efficiency, lowest emission levels, and ensure safety by using CO concentration measurements to fine tune their excess O 2 setpoint. These benefits are achievable only if the CO measurement is accurate and reliable. Using TDLS, the TruePeak Analyzer from Yokogawa can provide that accurate, reliable CO measurement in coal fired power plants.

Our oil/gas fired boilers can be divided into SZS water tube boilers and WNS fire tube boilers depending on the medium inside the tubes. With multiple pressure designs, the water tube boilers can meet the steam supply requirements of or above. The fire tube boilers, on the contrary, are intended for use at pressures below MPa. Fire tube boilers usually have a capacity of below 20t/h

Most coalfired power station boilers use pulverized coal, and many of the larger industrial watertube boilers also use this pulverized fuel. This technology is well developed, and there are thousands of units around the world, accounting for well over 90% of coalfired capacity. The coal is ground (pulverised) to a fine powder, so that less than 2% is +300 micro metre (µm) and 7075% is

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
