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.
7-3-1980· An improved nozzle tip for a pulverized coal-fired burner having one or more splitter plates disposed therein. Each splitter plate is formed of a first portion of highly abrasion resistant material disposed at the inlet end of the nozzle tip and a second portion of highly heat resistant material disposed at the outlet end of the nozzle tip.
Abstract- In this paper, mass flow rate of flue gas at inlet & outlet for pulverized coal power plant are analyzed with consecutive steps. For this required coal input for a specific power generation is determined with help of ultimate analysis of coal.
23-2-1983· A new and improved burner for pulverized coal comprises a tubular nozzle for containing a primary, flowing stream of coal/air mixture having an outlet for discharging the stream into a combustion zone of a furnace.

A coal-fired thermal power plant. The combustion air will be supplied to the burners by the forced-draft fan, and pre-heated the air to dry the pulverized coal. Mixture of the fuel and air will be burned in the furnace. From combustion, the heat recovered by the boiler generates steam at the specified pressure and temperature.
In the pulverized coal-firing boiler, the pulverized coal used for fuel goes through the following processes. (1) Pulverized coal is injected from the burner into the boiler furnace. (2) The pulverized coal particles are heated by radiation and heat transfer by convection, and the volatile matter is released.
The coal is ground (pulverised) to a fine powder, so that less than 2% is +300 µm and 70-75% is below 75 µm, for a bituminous coal. The pulverised coal is blown with part of the combustion air into the boiler plant through a series of burner nozzles. Secondary and tertiary air may also be added.
The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine.
