The Effect of Recovery Furnace
A commercially available computational fluid dynamics code has been used to simulate temperature and flow profiles in the upper, convective heat transfer region of a recovery boiler for different bullnose designs. The convective heat transfer region of the furnace was simulated by examining a zone that begins below the bullnose and ends at the economizer. Superheater tubes and a boiler bank wer...
متن کاملFurnace Wall Corrosion in a Wood-fired Boiler
The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals. These elements increase the corrosion problems at the furnace walls where...
متن کامل4.4-1 Recovery Boiler Chemical Principles
A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting sulphur and sodium are recovered from the black liquor, the recovery boiler then serving a...
متن کاملPower Generation Skills Development Module 4: Thermal power plant fuel and milling systems
Major furnace explosions have resulted in the deaths of personnel, extremely expensive repair costs and, in most cases, loss of revenue during the repair period. For a large power station boiler the total cost of a furnace explosion could easily be in the $10M to $20M range. The protection systems fitted to a modern boiler have been developed to the stage where boiler explosions are a rare occu...
متن کاملLatent Heat Recovery in Exhaust Gas of a Condensing Boiler: The Effect of Arrangement of Tubes
Boilers are one of the major energy consumers in the building. For this reason, increasing the efficiency of this device and improving its performance is an effective step in solving the problems in building energy and reducing waste energy. Due to the limited resources of fossil fuels and the increasing cost of energy in the world, manufacturers of these equipment are always working to improve...
