Steam Desuperheater Spray Calculator

Calculate boiler feedwater spray injection flow rate (GPM) for mechanical steam desuperheaters (Spirax Sarco / Schutte & Koerting) conditioning superheated steam under ASME B16.34: calculate enthalpy heat balance ($m_w = m_s imes [h_{in} - h_{out}] / [h_{out} - h_w]$), maintain safe saturation approach temperature ($10^circ ext{F to }20^circ ext{F}$ above saturation), and steam piping profits.
