1 would say late 40s. i started in the trade in 1957 and we serviced a bunch of them. information was almost none.they were pretty neat and were a down fired,low pressure burner. some follks installed high pressure gun type burners in them and down fired them.they were very efficient in their original state-80%+ and yes we did have testing
Low Pressure Boilers. Low pressure boilers are tanks or vessels that facilitate the transfer of heat from its source to water or steam at pressures below 15 PSI. Though high temperatures within an enclosed space result in increased pressure, these boilers are able to keep pressure at or below the atmospheric pressure of ~14.7 PSI.
The Low Pressure Boiler Tank is a semi-required component for creating a Steam Boiler from Railcraft. It is only semi-required because there is an alternative, the High Pressure Boiler Tank . A Low Pressure Boiler Tank will produce steam as efficiently as possible, consuming as little resources.
This boiler is a kind of fully automatic fire tube low pressure oil gas boiler, which has steam boiler, hot water boiler, thermal oil boiler and so on.
A scaled boiler can turn X into a big, unpleasant number. Don’t buy a boiler that can’t be solved for X or you’ll be asking yourself why. Scale: aka “lime” “mud” “sludge” “bane of man’s existence” – occurs when dissolved solids (the "hardness" in water) settle out in a pressure vessel. It’s the familiar process
• Minimum height for #2 oil or combination gas & #2 oil fired boilers is 15 ft. • The stack should be supported independently of the boiler and an ad- justable length section of stack should be installed after the barometric damper to allow for future separation.
Low-Pressure Boiler Definition In a low-pressure boiler the pressure does not exceed 15 psi, and hot water heating boilers are not designed to exceed over 260 psig. The temperature in a low-pressure boiler will not rise above 250 degrees F.

In the event of low water, the low water trips will trip the burner (or fuel flow for solid fuel boilers) and shut down the forced draft fan. This shuts down the heat input. A LOW-WATER CUTOFF IS A MAINTENANCE MUST!!! The trips should be installed at a water level that will prevent damage. Low-water trips are generally installed approximately 6” lower than normal operating level.
