The Aalborg KBSA steam atomising burner is designed for use on our side-fired boilers and can be delivered premounted. The use of oil flowmeter and modulation of the atomizing steam pressure ensures a stable combustion at all loads, also in the lower end. All burner mountings are arranged to ensure easyinstallation and maintenance.

The Alfa Laval Aalborg OC-TCi is a space-saving marine boiler for vessels requiring small to medium amounts of steam or hot water. As a composite solution, it has both a fired section and an exhaust gas section, allowing it to be heated through combustion and/or waste heat recovery.
Developed in-house, Alfa Laval Aalborg boiler solutions are tested and optimized at the Alfa Laval Test & Training Centre and thoroughly proven at sea. Our experts ensure high thermal efficiency and the correct steam balance for your vessel, as well as global access to boiler services. Choosing boiler connectivity lets you access our knowledge continuously, using it to safeguard uptime, enhance performance and lower your operating costs.
Preassembled and installed vertically, the Aalborg OC-TCi consists of a fired module with helix tubes and an exhaust gas module with smoke tubes. In the Aalborg OC-TCi Multiple Inlet version, the latter module is suitable for use with one main engine and two auxiliary engines. The boiler provides effective self-cleaning, thanks to its built-in TCi (Turbo Clean, intelligent) technology and its relatively high exhaust gas velocity compared to other composite boilers. It can also be fitted with a compact silencer to suit any type of diesel engine.
Alfa Laval Aalborg dual-fuel boilers are more than an efficient solution for your steam and hot water needs. Able to handle both free flow and methane mixed with inert gas, they provide safe, effective ways to manage boil-off gas (BOG) and simplify operations connected with tank inspection.
Built on a century of thermal expertise, Alfa Laval Aalborg boilers are prepared to run on methanol, thanks to our future-proof MultiFlame burner concept. Adding to our already extensive combustion knowledge, we are now conducting large-scale methanol testing at the Alfa Laval Test & Training Centre.
The electric FD fan actuator upgrade involves the installation of a small control cabinet close to the FD fan and a power cable connecting it to the boiler's local control cabinet. The upgrade kit contains the following:
Before delving into the tests, it is important to define boiler water. In short, boiler feed water is distilled water that is chemically adjusted. It floats through a closed system as depicted in the illustration bellow.
So what makes testing of boiler water so important? Well, boiler water abides by certain parameters in order to protect the boiler (and other engine compartments) from corrosion, as well as protect from a scaling deposit formation. To check these parameters and adjust the water, engineers test water samples regularly, using a testing kit which we discuss in the next chapter.
In the next few chapters, we will take you through the steps you need to follow when testing different boiler parameters, what these parameters mean, and why they are important. Finally, when it comes to marine water boiler treatment, we will also discuss the UNITOR chemicals you need to use to keep the parameters of the water in operational range.
For the next test, you are now going to check the phosphate levels in the boiler. Phosphate is important to maintain since it reacts with any calcium impurities within the water, and forms a precipitate that will accumulate at the bottom of the boiler. This can later be blown down or discharged (by releasing the bottom blow down valve).
Testing for Chloride is very important as it indicates whether sea water is contaminating the boiler. This causes increased conductivity between the boiler metal and its water, which accelerates oxidation.To start this test, fill the 100ml beaker with sample water. Next, dissolve chloride tabs one by one until the color of the water changes from yellow to brown. Depending on the number of pills we use, we can then determine the chloride concentration of the water (use the color indicator to determine the levels).To start this test, fill the 100ml beaker with sample water. Next, dissolve chloride tabs one by one until the color of the water changes from yellow to brown.

For this test, you will need to use the 200ml flask as well as the P&M Alkalinity tabs (indicator pills). P & M Alkalinity calculates the total amount of inorganic carbons inside the sample, which in turn indicates the total alkalinity in the sample. Remember that boiler water should be in an alkaline environment but not in excess, in order to promote the formation of precipitates and protect from corrosion.
P Alkalinity test in boiler water - Start by placing P indicator pills in the sample water (one by one) until the color changes from blue to yellow. Depending on the number of tabs added to the water you will be able to identify the P Alkalinity. (Formula: PAlk = P Alk Pills x 20 - 10 = ppmCaCo3)
M Alkalinity test in boiler water - This test starts with the same water sample you previously used to determine the P Alkalinity (yellow). Add M indicator pills consecutively until the color of the sample turns from yellow to purple. Then, based on the number of pills that were used, you will be able to calculate the M Alkalinity of the sample
Boiler water testing is primarily focused on the maintenance tasks mentioned above. That said, there are a few more procedures you can perform to further examine the condition of your boiler's water. Below, we discuss an additional boiler water test procedure that you can perform whenever the next round of maintenance occurs.
This test is performed to test the temperature of your boiler water and make sure it is within the prescribed limits. To perform this test, you will need to acquire a separate boiler water test kit from UNITOR known as SPECTRAPACK 309. While we won't delve into boiler water analysis procedure, we will offer a short indication of the levels you need to be looking at:
