Boiler Water Treatment Guidelines; Columbia Boiler Co

The pH should be maintained between a minimum of 10.5 and a maximum of 11.0 to prevent acidic corrosion of boiler tubes and plates, and to provide for the precipitation of scale forming salts before scale is deposited. Below a pH of 5.0 the water is acidic enough to dissolve the steel boiler plates. Under these conditions the steel gradually

Boiler Fuel - an overview | ScienceDirect Topics

Harry Perry, in Advances in Energy Systems and Technology, Volume 1, 1978 (1) H-coal Process. This process converts coal into either a low-sulfur boiler fuel or into refinery syncrude. Coal is slurried in a recycled oil and reacted with hydrogen at 3000 psi. The mixture is pretreated and pumped into the bottom of an ebullated bed catalytic reactor.


pitting can result with possible rupture of boiler condensate piping or boiler tubes. 3.3.4 Rusty water in the boiler gage glass is a sure sign of acid corrosion in the boiler feedwater/condesate system or in the boiler itself. 3.3.5 Make-up water is the major source of carbon dioxide. The first priority is to minimize the amount of make-up water.

The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry. Steam Purity. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.
