28/01/2015 · Start up is by oil burners in the furnace. Ash spouts in the furnace remove the ash from the bottom of the furnace. it is CFB boiler working principle. ZG is a circulating fluidized bed boiler manufacturer. The circulating fluidized bed (CFB) is a clean process with the ability to achieve lower emission of pollutants.
Steam Boiler | Working principle and Types of Boiler
Process: A water-cooled lance with a special bag is introduced through doors or portholes into the boiler near the heating surface to be cleaned. The bag is inflated and the combustible mixture ignited. The resulting shock waves or vibrations of the tubes and walls dislodge deposits of ash and silt.
Wall box an attachment to the boiler wall at the opening made for the cleaning device. It provides structural support for the cleaning device and helps to minimize flue gas escape to the atmosphere when the lance is retracted. Feed tube the stationary tube that feeds the cleaning medium to the moving lance tube or rotating element.
A boiler is a closed, pressure vessel in which water is being converted to steam (and possibly superheated) by the transfer of energy from a fuel source typically oil, gas, or coal. The steam exits the boiler for use in various processes or heating applications such as manufacturing equipment, central heating, steam-based power generation, cleaning, cooking, and so on.
opened during the running of the boiler, the high-pressure steam pushes the water and the collected material at the bottom is blown out. Blowing some water out also reduces the concentration of the salt. The blow-off cock is operated after every 5 to 6 hours of working for few minutes. This keeps the boiler clean. 6. Steam Stop Valve
