Boiler Efficiency and Steam Quality: The Challenge of

High velocity steam, exceeding 120 ft/sec, (7,200 ft/min) causes a number of problems, including erosion of piping and other components, and noise in piping. Steam velocity is a function of flow, pressure, and internal pipe diameter. The following formula shows this relationship.

Boiler Capacity - Engineering ToolBox

Mar 17, 2015 · Steam Mass Flow = Feedwater Mass Flow - Feedwater Mass Flow * Blowdown Rate; Feedwater Mass Flow = Steam Mass Flow / [ 1 - Blowdown Rate] Using the Steam Property Calculator, properties are determined using Deaerator Pressure and Quality = 0 (Saturated Liquid). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Feedwater Energy Flow = Specific Enthalpy * Mass Flow; Step 3: Determine Blowdown Properties and Mass Flow Using the calculated feedwater mass flow …

Effective Boiler-Level Control | HPAC Engineering

Steam can be raised at a quicker rate with large water capacity The hot gases flow toward the direction of water flow, so the maximum amount of heat is transferred to the water Bursting of one or two tubes does not greatly affect the boiler, so water tube boilers are sometimes known as safety boilers
