Boiler (power generation) - Wikipedia
Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork

Boiler Ratings and Boiler Load - Alken-Murray
Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions. Maximum continuous rating is the hourly evaporation that can be maintained for 24 hours. To convert horsepower (hp) into lbs of steam: Multiply hp x 34.5 Example: 100 hp x 34.5 = 3450 lbs

Steam Boiler - Definition, Working Principle, Types, and
Steam Boiler The Function of Steam Boiler . The main function of a steam boiler is to producing, storing and troubling the vapor. The liquid contained boiler is nothing but a shell and the heat energy produced while burning of fuel will be moved to water, and then it converts into steam at the required pressure as well as temperature.

How do you Size Steam Main Vent? — Heating Help: The Wall
In buildings like yours operating steam pressures are a major factor. If your system operates under 2 PSI you can use 2 Gorton # 1 vent valves. each vent valve releases 4 cubic feet of air per minute. The 2 vent valves will release a total of 8 cubic feet of air per minute. Steam will move pretty quickly down the steam main at that venting rate.
