2012-12-4 · Kong, a certificate issued in respect of the boiler or pressure receiver by a recognised inspecting authority in the country in which it was constructed. Before it being put in use the equipment under the above Ordinance must be examined by a Boiler Inspector appointed under the Boilers and Pressure Vessels Ordinance, Cap. 56.
Read MoreSteam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

The shell boiler contained all the necessary feed water systems, blowdown systems and standard safety controls. The unit
Read MoreSewage disposal methods and requirements for regular steam boiler blowdown in use, but many users ignore this point, the sewage can often greatly increase the life of the boiler, the following with you to introduce requirements and methods of steam boiler blowdown. 1, continuous blowdown: continuous blowdown called surface discharge.
Read MoreBoiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.

Read MoreBoiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.
Read MoreThe specific method of chemical treatment used varies with the type of boiler and the specific properties of the water from which the boiler feed is derived. This is very site specific but Lenntech has the testing capability to cover all your requirements. A boiler requires testing of three different water types as shown below: Feedwater

The steam blanket excludes oxygen, thereby minimizing the potential for corrosion in the boiler. Boilers under a steam blanket require a blowdown because the steam applied to the boiler condenses and increases the boiler's water level. A blowdown
