May 25, 2016 · Then on December 6, 1906 a boiler in the factory of the P.J. Harney Shoe Company exploded in Lynn, Massachusetts. As a result, the state of Massachusetts enacted the first legal code based on ASME's rules for the construction of steam boilers in 1907. As catastrophic casualties continued, the ASME developed its boiler code in 1914.
Article 213-1. Water quality of condensate water, feed-water and boiler water 1. Purpose of feed-water treatment The purpose of the water quality control (feed-water, boiler water) is to prevent the scale adhesion in the boiler, steam turbine system and other ancillary system due to the water quality of water …
For boilers having a water-heating surface of 100 ft2 (9.3 m2) or less, the feed water connection to the boiler shall be not less than NPS ½ (DN 15). Boilers with 20 ft2 (1.9 m2) or less of water heating surface may have the feed water delivered through the blow-off opening.

The AGA cooker oven is a Swedish oven and cooker. Invented and initially produced in Sweden, since 1957 all production has been located in the UK. History. Originally developed to burn coal or anthracite, the Aga cooker was invented in 1922 by
Feedwater and boiler water residuals provide an indication of excess scavenger feed and verify chemical treatment feed rates. It is also necessary to test for iron and copper oxides in order to assess the effectiveness of the treatment program.
Generally it is desirable to have a slightly high pH for boiler feed water. Ideally the feed water should be in the range of pH 8.5 – 9.5. This ensures that free carbon dioxide within the system becomes 'fixed'. If copper fed lines or heaters are used, restrict the feed water pH to a maximum of 9.2.
