The International Boiler and Pressure Vessel Code establishes rules of safety governing the design, fabrication, and inspection of boilers and pressure vessels, and nuclear power plant components during construction. The ASME - American Society of Mechanical Engineers - International Boiler and Pressure Vessel Code (BPVC) is made of 11 sections
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

The steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam. It wasn't until around 1867, with the development of the convection boiler, that the steam-generating industry

Steam Generator Design Presentation - Boilersinfo
In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.
2016/9/20 · Rigorously inspect the heating system and rectify any problems. Clean and inspect the heat exchanger of the boiler. Ensure all boiler connections and wiring is intact. Make sure water pH levels are within the proper range. Inspect condensate system and clean and flush the system as necessary. Examine and clean flame sensors, ignitor, and burner
