The ASME developed its boiler code in 1915. The code provided a solid reference of construction standards, but ASME lacked the authority to regulate. This was further complicated by the existence of local and state jurisdictions with their own codes and standards. This resulted in a patchwork of confusion having no basis in consistency.

The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. [1] The document is written and maintained by volunteers chosen for their technical expertise . [ 2 ]
Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited. Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008. [10]
The upper sheet of the inner firebox on a locomotive boiler. It is the hottest part of the firebox, and sometimes at risk of boiler explosion, should the water level drop and the crown sheet be exposed and thus allowed to overheat. Supported from above by complex stays. Damper An adjustable flap controlling the air admitted beneath the fire-bed.
A typical Cochran boiler, as illustrated, [5] might be 15 feet (4.57 m) high and 7 feet (2.13 m) in diameter, giving a heating surface of 500 square feet (46.45 m 2), and a grate area of 24 square feet (2.23 m 2). Working pressure is between 100 and 125 psi (6.9 and 8.6 bar; 690 and 860 kPa).
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value ) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
