CONDENSATE TANK

The main features of such a Condensate tanks are:

Collecting the returned condensed Steam.
Heating the water supply through the
built - in heating unit " Make Up ".
Eliminating of a certain percentage of Soft
Oxygen and Carbon Dioxide.
The Condensate Tank can also be considered
as an alternative for the "Water Feed Tank"

BLOW DOWN TANK

When the Steam Boiler is fully operated much precipitation,
mud and calcification may exist at the bottom of the boiler,
which need to be extracted out the "Blow Down Valve".

Hence, these impure extracted elements from the boiler may cause some nuisance and/or damage the sewage system at the location.

This tank works on separating these foreign impurities through the bottom of the tank, and sends evaporated water through its vent outlets into the outside air.

DEARATOR

(CONDENSATE, FEED WATER TANK with DEARATOR)

After water has been filtered by the "Water softener unit" for the purpose of providing the boiler with suitable water to produce steam free of impurities, this filtered water "Soft Water" will still have different harmful gases; Worst of which will be Oxygen and Carbon Dioxide. Thus, the best way of eliminating these gases from the feed water before it reaches the steam boiler is through a "Dearator".

When water evaporates, it launches Oxygen at very high speed causing minute wholes on the surface of the metal that it bombards.
As for the Carbon Dioxide, it forms carbonic acid which in turn has a negative effect over the boiler metals and could lead to " Corrosion ". The Dearator (as per the figure below) consists of Horizontal tank that heats water up to 104^oC and frees Oxygen and Carbon Dioxide through the upper tank, whereas water and steam are sent to the opposite direction " Counter Current ". In this manner, evaporation and freeing of gases take place at the upper level of the tank "Tower- Ejector" and water is provided free of harmful gases.

BURNERS

The most suitable Burner type to be chosen for any steam boiler depends on
" Fuel Consumption at Full Load ", and " Boiler Back Pressure Resistance " .
Below are the relevant information needed to chose the right burner for each Steam Boiler:

Boiler Model / Capacity	Boiler Back Pressure mbar	Oil Consumption at 100% Load
Boiler Model / Capacity	Boiler Back Pressure mbar	Light Oil Kg/h	Heavy Oil Kg/h
200	3.5	12.5
250	3.5	15.6
325	3.5	20.3
400	3.3	24.9
500	3.2	31.2	32.4
