Call us at (714) 632-1193 when your boiler or water heater is down.  We’ll dispatch a qualified technician that will work diligently to get your boiler back online as quickly as possible.

And if we’re able to get the boiler back online in an hour or two, we won’t hit you with a 4-hour minimum charge.

Heat Transfer Solutions is well versed in the compliance requirements for all air pollution control district rules throughout California.  We have experience retrofitting atmospheric or power burners to any emissions standard.  Because we represent numerous boiler and burner manufacturers, we have direct access to the latest technology for NOx reduction.

When a boiler is generating steam, the feedwater continuously carries dissolved mineral matter into the unit. To prevent an excessive accumulation of dissolved and undissolved solids which interfere with proper boiler operation, a blowdown program should be established.  Blowdown heat recovery systems recover up to 90% of the heat energy that would otherwise be lost down the drain. The recovered heat is used to pre-heat boiler make-up water before it enters the deaerator, and for low pressure steam to heat water inside the deaerator, which reduces the cost to run the deaerator and improves overall boiler efficiency.

When a boiler is generating steam, the feedwater continuously carries dissolved mineral matter into the unit. To prevent an excessive accumulation of dissolved and undissolved solids which interfere with proper boiler operation, a blowdown program should be established. Blowdown separators take water from the boiler during blowdown and reduce it to atmospheric pressure for disposal.

Operation

Makeup water and pumped condensate returns are pumped into the deaerator stainless steel header box. The undeaerated water then passes through several stainless steel spray nozzles which form thin conical sheets of water that contacts steam where it is heated. This heating effect partially releases the dissolved oxygen and other non-condensable from the water. The continuous vent valve then exhausts these released gases to atmosphere. The partially deaerated water then begins to cascade through the trays where additional heating and deaeration occurs.

Steam entering the deaerator flows upward through the stainless steel trays in a counter flow direction where it scrubs the remaining dissolved gases from the water in a final polishing action and heats to near the saturation temperature. High-temperature returns enter the deaerator directly and release flash steam which also flows upward through the deaerator trays supporting the deaeration as well. The deaerated water then drops into the storage section where it remains until needed by the boiler.

Features

• The counter flow tray design provides removal of all dissolved oxygen in excess of .005 cc/liter from 5% to 100% of the deaerator capacity.
• Multiple configurations are available from vertical single tank vessels, standard “tank car” vessels or separate dual parallel horizontal vessels.
• Only stainless steel components come in contact with undeaerated water. Both the trays and tray boxes are constructed of stainless steel.
• All vessels are ASME Code stamped as per Section VIII 50 psig design pressure unless specified otherwise.
• Custom engineered packaged systems available to 600,000 lbs/hr. Larger deaerators to 2,000,000 lbs/hr capacity available as unassembled components for field.

Advantages

• Counter flow tray type deaerators are capable of accepting high percentages of condensate returns without adverse effects on performance. This is possible because the deaeration process does not require a flow of steam for scrubbing. All second stage scrubbing is done by the cascading process through the trays. The counter flow design provides maximum performance because the cleanest incoming steam contacts the water that requires final deaeration, stripping out the last traces of oxygen.
• Performance is guaranteed at all loads from 5% to 100% of rating with sizes ranging from 20,000 lbs/hr to 2,000,000 lbs/hr.

Operation

Incoming undeaerated water and pumped returns enter the deaerator through spring-loaded stainless steel nozzles which directs the flow in conical sheets into the steam atmosphere of the direct contact vent condenser. This incoming water temperature is raised to within a few degrees of steam temperature and most of the air and other non-condensable gases are removed in this first stage. The partially deaerated water then flows first into a collector basin and then down thru a baffle tube where steam flows in a counter flow direction. This flow of steam scrubs most of the remaining air and non- condensables from the deaerated water in a polishing action. The liberated air and non-condensibles exit the deaerator condenser thru the continuous vent valve. The heated and deaerated water then falls to the storage compartment where it remains until it is pumped to the boiler.

Features

• The spray-scrubber design provides for removal of all dissolved oxygen and other non-condensibles in excess of .005 cc/liter and heats the water to near steam temperature.
• Multiple configurations: vertical or horizontal vessels provide versatility in footprint size and space utilization.
• ASME Code stamped vessels for 50 psig design pressures is standard with optional pressures available.
• Custom engineered packaged systems are available as well.

Advantages

• The Spray- scrubber design allows for a low profile system design to accommodate pump net positive suction head requirements. This design provides very good deaeration performance at the lowest cost. Guaranteed performance to .005 cc/liter at all load points.
• Custom design packaged systems available.
