make the orifice plate. The plate is drilled with 17 holes of increasing size. See the flow charts on pages 3 and 4 for the actual hole sizes and the blowdown rate for each hole at various boiler pressures. The orifice plate is heat treated to 500 brinnell hardness and lapped to a mirror finish with a tolerance of three light bands (.00003").

Boiler – Fundamentals and Best Practices

Basic Boiler Calculations • Feedwater = Make up + Condensate Return • Feedwater Flow (FWF) = Steam Make + Blowdown(BD) • Feedwater Flow (FWF) = Steam Make + Steam Make • Cycles -1 • Blowdown = Steam make or = FWF • Cycles –1 Cycles • % Blowdown = 1 as a % of FWF • Cycles

Principle: The principle of operation of a safety valve depends on the fact that a valve is pressed against a seat through some external force. When the steam force corresponding to boiler pressure acting under the valve exceeds the external force, the valve gets lifted off its seat allowing some of the steam to escape until the working

Venturi effect - Wikipedia

boiler is not a compact fluorescent lamp (CFL); you can't simply plug it into a typical system and expect it to save energy. Selecting a condensing boiler is the easiest and least consequential part of designing a condensing boiler system. This paper provides basic principles for designing a heating system utilizing condensing boilers.

Boilers 291 Coagulation—a method for concentrating and removing suspended solids in boiler feedwater by adding chemicals to the water, which causes the impurities to cling together, p. 301. Condensate—condensed steam, which often is recycled back to the boiler, p. 294. Damper—a movable plate that regulates the flow of air or flue gases in boilers,
