Chemical water supply system of Boiler

   There are many calcium and magnesium salts in tap water, and the water quality is hard. If it is not softened, it will be directly added to the boiler, which will cause precipitation of calcium carbonate, magnesium carbonate and magnesium hydroxide, which will deposit on the inner wall of the water pipe/water bladder. Thermal efficiency, long-term past, boiler thermal efficiency will be lost. Chemical water supply system of Boiler focused on removal or chemical modification of substances potentially damaging to the boiler.qb6Horizontal boiler

  Chemical Water supply system includes soften water system, desalted water system, deaerator, water feed pump, water tank, dosing device, etc.qb6Horizontal boiler

  1. To select a water treatment equipment, users are required to provide boiler water quality reports (well water, tap water, surface water, etc.);qb6Horizontal boiler

  2. Boiler water treatment system: type selection: For steam boilers, the capacity should be greater than boiler evaporation; For hot water boilers, the feed up water capacity generally depends on the amount of circulating water in the system.qb6Horizontal boiler

  1) Sodium ion exchanger, salt tank, etc.qb6Horizontal boiler

  2) Fully automatic water softener: the requirement of inlet water hardness should be less than 8 mmol/L;qb6Horizontal boiler

  Industrial boiler (pressure less than 2.5 MPa): the outlet water hardness should be less than 0.03 mmol/L;qb6Horizontal boiler

  Main parameters: outlet water flow rate (8t/h, 10t/h, etc.), outlet water quality, double (single) valves and double tanks and other technical parameters.qb6Horizontal boiler

  3. Main parameters for Reverse Osmosis(short for RO) water treatment system: technical parameters of outlet water flow rate(60t/h, 100t/h, etc.), outlet water quality, etc.qb6Horizontal boiler

  4. Deaerator: Thermodynamic deaerator (including deoxygenation water pump; control cabinet), pressure deaerator, sponge iron deaerator, analytical deaerator, etc. Boilers above 10t/h require matched deaerator.qb6Horizontal boiler

  The deaerator is divided into low level deaerator and high level deaerator.qb6Horizontal boiler

  5. Water feed pump: the selection is mainly based on the boiler pressure and system resistance.qb6Horizontal boiler

  Water feed pump mainly includes vertical pumps, horizontal pumps, etc.qb6Horizontal boiler

  Main parameters: flow rate, pressure, rotating speed, matched Variable Frequency Motor or Ordinary Motor (power), etc.qb6Horizontal boiler

  6. Water tank: Volume size; Carbon steel, stainless steel (combined type) or other type.qb6Horizontal boiler

  7. Ammonia feeding device and dosing device are mainly used to adjust the boiler water index.qb6Horizontal boiler

  Parameters: pressurized flow rate and pressure; generally there are two pumps and one tank (including control cabinet); two pumps and two tanks (including control cabinet).qb6Horizontal boiler
