Learn MoreSome flue gas spill detectors actively detect flue gases or carbon monoxide but the simplest models respond to temperature by detecting the hot gases associated with flue gases on gas …
Learn MoreAnswer (1 of 6): Typically boilers of much size would have a steam meter that calculates flow. This is typically a sensor measuring the pressure drop across and orifice. If you don't have that, then you have two options. Option one is mainly for firetube style boilers. If
Learn More2015/3/17 · Step 1: Determine Properties of Steam Produced. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow
Learn MoreOther methods to control steam temperature are through the use of flue gas circulation, flue gas bypass, or the tilting angle at which the burners fire the furnace. The simplest method for controlling steam temperature is to monitor the temperature of the steam as it exits the boiler and change the position of the spray water valve.
Learn MoreHeat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to chemical process require…
Learn MoreFlue gas pretreatment is needed, which generally consists of two sections: one dedicated to NO 2 and SO 2 removal, and one dedicated to flue gas water saturation and cooling to 30–40 C. In addition, the implementation of a wet electrostatic precipitator can significantly reduce SO 3 aerosols, fine water droplets, and small particles.
Learn MoreFlue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.
