pulverized coal is air-blown into the furnace from fuel nozzles at the four corners and it rapidly burns, forming a large fireball at the center. the thermal radiation of the fireball heats the water that circulates through the boiler tubes near the boiler perimeter. the water circulation rate in the boiler is three to four times the throughput and is typically driven by pumps.
for energy production, coal pulverizers or mills are used to grind coal into a fine black powder so that the furnace can more easily burn it. primary air feeds the coal pulverizer and acts as a carrier and dryer for the coal moving to the burner. an exhaust fan pulls the coal dust
primary air feeds the coal pulverizer and acts as a carrier and dryer for the coal moving to the burner. an exhaust fan pulls the coal dust from the pulverizer and blows it through pipes into the furnace, where it ignites to heat the boiler water. secondary air is used to maintain the furnace flame and tertiary air surrounds the boiler wall.
the mill’s air supply system includes a venturi air flow meter , fan and natural gas direct-fired heater to supply a measured amount of hot air to the pulverizer to dry and transport the coal. methane de
in flow energy management, for example, sierra instruments became a single-source supplier by offering three types of flowmeters that measure gas, steam, air and water. multivariable vortex meters measure as many as five process variables: volumetric flow, mass flow, density, pressure and temperature. companies build on flowmeter advancements
