Section 23 52 33 - WATER-TUBE BOILERS
3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.

Boiler Feedwater - an overview | ScienceDirect Topics
Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

Boiler water treatment - Lenntech
The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too high to be tolerated by the

New Application Overview: Monitoring Dissolved Oxygen in
Proper water quality maintenance maximizes operating efficiency and the lifespan of boiler equipment. Maintaining Water Quality in High-Pressure Boilers Dissolved oxygen, or DO, is one of the most important water quality parameters to control in a boiler system. It is the primary corrosive agent of steam-generating systems.

Water Treatment for Boilers and WSC Chemistry
Water treatment program for boiler systems Water treatment = preventative maintenance program to minimize corrosion and scale in the boiler and carry over/deposits on the turbine. Well designed water treatment program can significantly reduce your energy, water, and maintenance costs while ensuring safe and reliable operation. Small reductions in boiler or condenser efficiency - huge increases

Maximum total alkalinity consistent with acceptable steam purity. If necessary, should override conductance as blowdown control parameter. If makeup is demineralized quality water and boiler operates at less than 1000 psig (6.89 MPa) drum pressure, the boiler water conductance should be that in table for 1001-1500 psig (6.9-10.34 MPa) range.

Boiler Water Quality
Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica.

The concentration of phosphate in boilers water is dependent on drum pressure and water quality, a typical high pressure boiler fed with de-mineralized water would tend to run with low concentration of 1 to 5 mg/l range, while a lower pressure boiler running with softened water might go to 25 mg/l.
