A boiler with a steam rating of 200,000 lb/hr will be fired with the above fuel having a high heat value of 12,200 BTU/lb. if the boiler efficiency is 80%, and if it takes 1000 BTU to evaporate and superheat one pound of feedwater to the desired temperature, find the hourly coal supply and grate area neened.Get Price
Boiler safety is of utmost importance in view of the large amount of energy stored in the form of superheated water. The boiler water, which is heated above its atmospheric pressure boiling point, will flash-boil to a very large and destructive volume of steam should the boiler suffer structural failure precipitated by too low a water level.Get Price

Corrosion is one of the main causes of reduced reliability in steam generating systems. It is estimated that problems due to boiler system corrosion cost industry billions of dollars per year. Many corrosion problems occur in the hottest areas of the boiler-the water wall, screen, and superheater tubes.Get Price

The plant is designed to combust woodchips by conveying and blowing the woodchips onto a travelling grate within the boiler. The spent steam from the turbine is condensed in a condenser cooled with water from a cooling tower using grey water, extracted under license, from local boreholes and treated process-effluent.Get Price
Nov 24, 2016 · Q (P).Describe 'chain grate' and 'spreader stoker' type boiler. Chain-Grate or Travelling-Grate Stoker Boiler Coal is fed onto one end of a moving steel grate. As grate moves along the length of the furnace, the coal burns before dropping off at the end as ash. Some degree of skill is required,Get Price
A steam locomotive is a rail vehicle that provides the force to move itself and other vehicles by means of the expansion of steam.: 80 It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point when it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels.Get Price
Nov 24, 2018 · Coal is used as powder condition in pulverized coal fired boiler. So lot of soot is deposited in this type of boiler. Frequency of soot blowing at an interval of 8 to 10 hours is required in this cause. In case of oil and gas fired boilers ash percentage in fuel is very less so soot deposits is very negligible.Get Price
The current efficiency gap is largely one of deployment as opposed to technology availability: the efficiency of modern boiler packages with integrated heat recovery can exceed 85%, while advanced system monitoring and controls, coupled with best-available process heating equipment, can reduce overall steam demand to its practical minimum value .Get Price
Sep 20, 2012 · The boiler was used occasionally to steam the engine for interested viewers at my house in the large shed in the back garden, fired both by diesel burner, then later on, by dry timber. The boiler was always maintained full of treated water and generally under a vacuum between firings, and is in as-new condition internally.Get Price
