Improvement in coal quality can'also lead to operating problems in a pulverized-coal-fired boiler. If a nonslagging coal is burned in a boiler designed for a slagging coal, furnace walls may be too clean, and too much radiant heat may be absorbed, which makes it difficult for the superheater to produce the necessary steam temperatures.
start-up and operation steam boilers warning: improper servicing and start-up of this equipment may create a potential hazard to equipment and to operators or persons in the building. servicing and start-up must be done only by fully trained and qualified personnel. caution: before disconnecting or opening any fuel line, or before cleaning or
Our engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to make a hot water boiler specifically designed to burn coal and built them in multiple sizes to meet our customers' needs.
Sep 02, 2017 · AFBC ( Atmospheric Fluidized Bed Combustion ) BOILER COLD START UP PROCEDURE:-AFBC boiler is a very developing technology now these days this technology is widely used in the industrial boiler for the purpose of efficient and clean burning of coal and other fuel for steam generation. afbc boiler is suitable for combustion of low quality fuel .

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

The loop will allow hotter water, stored in the top of boiler to flow naturally to lower part of the boiler. This will maintain a more even boiler temperature and reduce chance of overheating water. 2. Installing a loop will prevent boiler shock. When circulator runs cooler water from return, the line will not all dump into boiler.
