How to Run a Coal Fired Boiler at the Best Efficiency

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.

Pulverised Fuel Flame Monitoring in Utility Boilers

pulverised fuel (PF) fired boilers is the provision of reliable flame monitors. If a flame in a boiler is inadvertently extinguished whilst fuel continues to be supplied there is the risk of an explo­ sion with serious consequences to both personnel and equipment. If such potentially dangerous situations are to be eliminated the flame monitors

Inhibition of lignite ash slagging and fouling upon the

In this paper, we, for the first time report the properties of ash deposits collected from the combustion of lignite mixed with silica additive, in a 30 MW th pulverised-fuel boiler with sub-critical steam conditions. The combustion test was carried out continuously over ten months, and ash deposits were sampled from various locations in the boiler.

Pulverized Coal Firing Advantages in Thermal Power Plant

The external heating surface is free from corrosion and fouling as smokeless combustion is possible; There are no moving parts in the furnace or boiler subjected to high temperature. Therefore the life of the pulverized fuel firing system is more and operation is trouble-less; Practically no ash handling problem in this type of firing system

Modern Boiler Types and Applications - KTH

Pulverized coal fired boilers, which are the most popular utility boilers today, have a high efficiency but a costly SOx and NOx control. Almost any kind of coal can be reduced to powder and burned like a gas in a PCF-boiler. The PCF technology has enabled the increase of boiler unit size from 100 MW in the 1950's to far over 1000 MW.

Pulverised Coal Combustion with higher efficiency

This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C. This steam is passed into a turbine to produce electricity (see Figure 1). Pulverised coal power plants account for about 97% of the world's coal-fired capacity (IEA 2008, p. 225).
