Wherever a pressure is quoted in terms of bar, it refers to bar (gauge). The maxima given relate to normal steady state operation and they will be exceeded during start-up and also possibly during significant load changes. These values are recommended for fully softened feed water in accordance with the table. At these heat fluxes it is recommended that the caustic alkalinity be maintained at 10 % to 15 % of the total dissolved solids concentration if phosphate conditioning is practised. The hexavalent chromium in this wastewater must be reduced before the water can be discharged. Performs pure water compensation in the analysis of demineralized water, steam, condensate, and boiler water. Removal of free oil and grease from a wastewater stream reduces the potential for equipment problems downstream. In view of the great variety of boiler designs in this category it is not possible to stipulate the precise feed water characteristics required for all boilers. The sensors measure organics in a multi-dimensional way that results in improved correlations to aggregate organics water quality parameters, such as BOD and COD. Flow and pressure loss in condensate return lines - SI Units. The boiler manufacturer should state the maximum total dissolved solids (TDS) in the boiler water at which the required steam purity can be obtained. Chemical Oxygen Demand is an important water quality parameter because, similar to BOD, it provides an index to assess the effect discharged wastewater will have on the receiving environment. If the feed system is completely ferrous, the ph should be limited to 9.2 to 9.5. As the water become purer, the voltage differential begins to exceed 2 volts, splitting the water molecules. This data should be augmented by determination of the concentrations of dissolved metals and the presence or absence of debris, e.g. What can be the maximum possible distance from SA11 to HMI/PLC? Recommended water characteristics for shell boilers up to 30 bar (continued) NOTE 1. Can the contacts be used to drive a pump? A water tube boiler is an energy efficient package with the boiler feed water passing through an economizer to the boiler.

[4], At the elevated temperatures and pressures within a boiler, water exhibits different physical and chemical properties than those observed at room temperature and atmospheric pressure. Maintenance of a phosphate reserve is not essential provided either that a minimum carbonate alkalinity of 250 mg/kg can be maintained, depending on the alkalinity of the feed water and the working pressure of the boiler, or that an appropriate programme of transporting polymers is employed. Cookies are only used in the browser to improve user experience. Separator drain water can be returned to the feed water tank or dumped, or the feed water can be added to the separator drain for recycling through the coil(s). Vertical sidelining on replacement pages indicates the most recent changes (amendment, addition, deletion). The table gives typical values for some common chemical scavengers. 2.3 Hot water systems General Because more than one approach to water treatment exists for hot water systems, each of which gives varying degrees of protection to the system, the approach most suited to the system should be selected after consideration of its type, age and condition in order to provide the most cost-effective regime. When using the BA11 it is possible to extend a further 100 meters. An oxygen scavenger should be used (see 5.3.2) and should be added at the outlet of the feed tank or the deaerator in sufficient quantity to reduce the dissolved oxygen level to zero before the feed water enters the boiler or the economizer (where fitted). Where the available water contains more than 10 mg/kg of each anion, demineralized water should be used. Hydrolysis of trisodium phosphate is a pH buffer in equilibrium with disodium phosphate and sodium hydroxide.
