ECOTHERM Steam Solutions 11 Products: Feed Water Tanks

Feed Water Tanks & Deaerators

Description The feedwater deaerating plant, consisting of the feedwater tank and the deaerator, removes dissolved gases such as oxygen, carbon dioxide and other non-condensable gases from boiler feedwater and makeup water. For the operation of steam boilers with high thermal load on the heating surfaces boiler feedwater must be treated and conditioned. The boiler feedwater must be free of hardening constituents in order to prevent the formation of scale on the boiler heating surfaces. The presence of dissolved oxygen and carbon dioxide causes severe corrosion of metal boiler parts. The feedwater deaerating plant is custom designed for each application and meets essential thermodynamic requirements to achieve optimal performance.

Function The make-up water and return condensate enters the deaerator that is fitted with a series of tray compartments to provide maximum spilling. Heating steam is fed into the deaerator from below. The make-up water and return condensate are deaerated and flow directly into the feedwater tank, which is flanged to the deaerator. The feedwater tank, which is heated by means of a steam injector, heats up the feedwater to 105°C. The solubility of gases in water can be described by Henry Dalton‘s law of absorption which states that gas solubility in a solution decreases as the gas partial pressure above the solution decreases. This means that the gas solubility in a solution decreases as the temperature of the solution rises and approaches saturation temperature. The make-up water and return condensate is distributed over the series of trays and comes in direct contact with the heating steam. This process reduces the solubility of oxygen and carbon dioxide and removes these gases from Technical details on pages 48 - 49. the feedwater. The released gases work their way to the top of the vessel where they are vented from the deaerator via the vent line.

ECOTHERM Steam Solutions 13 Products: Blow Down Coolers

Blow Down Coolers & Flash Vessels

Steam boilers must be blown down to remove contami- nants, as a too high level will cause foaming and scaling of the boiler tubes. A build-up of solids at the bottom of the boiler could also have serious consequences. Most mo- dern boilers are fitted with TDS controls to remove dissolved solids, and a blowdown valve that is opened at regular intervals to remove precipitated solids. Because the bottom blowdown valve is opened just a few seconds per day, it is not economical to recover the heat, yet water cannot be discharged to drain unless it is cool. Nowadays, blowdown vessels have replaced blowdown pits as the recommended way of cooling this water. Blowdown from TDS controls should ideally be connected to a heat recovery system inside a flash vessel. Where this is not practical, TDS blowdown may also be piped to a blowdown vessel.

User benefits: • Three inlets as standard with dedicated bottom blowdown and TDS connection. • Fully complies with the requirements of the European Pressure Equipment Directive 97/23/EC. • Complete systems normally readily available from stock. • Quick and easy to install and maintain.

DISCHARGING AIR AND OXYGEN TO VENT out of building For flash vessels an internal heat recovery system is provided.

Important factors for sizing of blown down coolers & flash vessels: • Boiler pressure • Number of boilers • Duration of blow down DRAIN • Blown down line size • Length of blow down line between the boiler and the blow down vessel • Blow down regime

Pressure Reducing Stations

It is more efficient and economic to produce steam at high pressures ready for delivery through the distribution system. This may mean that the pressure needs to be reduced prior to the point of use or for different parts of the system. A reliable method of providing pressure reduction is to use a pilot operated pressure reducing valve station. Every pressure reducing station is custom designed according to required steam flows and pressures.

ECOTHERM Steam Solutions 23 Products: Vapur Heat Exchangers, Water Heaters

Vapour Heat Exchangers

The ECOTHERM vapour heat exchanger is used for: • Pre-heating of boiler feed water • Condensate relief • Degasification of fresh softened water and condensate • Flash steam heat recovery

For this process, thermal degasification, steam is used which deaerates the gases (N2, O2, CO2) out of building. Hence there is energy lost on deaerator.

This “lost energy” can be used for pre-heating of cold softened water or domestic cold water.
