Komax Scepter Steam-water Mixing System similar to a Steam Sparger
This versatile series of steam heaters is designed for the direct injection of steam into tanks for heating water compatible products:
– In a quiet
– Vibration free, and
– 100% efficient fashion.
– In addition, the sparger tank heater develops a strong stirring action to help keep any solids or particulates in suspension.
– This stirring action also helps to produce uniform temperature throughout the tank volume allowing accurate thermostatic control.
CUSTOMERS PROBLEM: STEAM INJECTION TANK HEATING.
Northwood pulp and Timber Company in Prince George British Columbia, was plagued with a problem of violent vibrations and banging when heating a large volume paper machine chest with a conventional steam sparger. The tank walls were lined with ceramic tiles which were cracking, sections were coming off the wall due to the vibration from the collapsing steam bubbles.
Bill Neville, the Plant Engineer, contacted the Komax Systems representative, Austin & DenholmInc., in Vancouver. ADI recommend installing a Komax “Scepter” direct steam tank heater. After the Scepter installation the vibration and banging totally disappeared.
A major industrial account in the state of Maine needed to heat a large rectangular tank of water in less than 30 minutes to provide quick start-up to their production. After seeing the simplicity of the Komax “Scepter” direct steam tank heater with no moving parts they ordered one.
RESULTS OF KOMAX SCEPTER DIRECT INJECTION STEAM HEATER
The 6 inch diameter Scepter Heater was installed in August 1999. The unit operates with no vibration, noise or water hammer. The direct steam injection Scepter increases the temperature of the water from 80 degrees to 140 degrees F. Based on standard steam spargers the plant engineers had calculated the heating time would be at least thirty minutes. The engineer in charge of this new installation was amazed that the Komax Scepter Heater was able to achieve the temperature increase in just six minutes!!! This time savings has led to a quicker overall startup for their system and has been a significant money saver for the customer.

Design Example for the Komax Scepter direct injection steam heater
We have a tank volume of 10,000 gallons containing a water like product and wish to raise the temperature by 50° F in 30 minutes with 40 psig steam available. Our temperature rise is 100° F/hour. Enter the design graph at 10,000 gallons and move to the right to intercept the 100° F/hour line giving the saturated steam flow rate M required as 7,000 pounds/hour. Now move down this steam flow rate line to meet the 40 psig intercept. The graph shows we’ll need a three-inch pipe size heater.
Komax sceper heater in biogas industry (digester)
The processes in the manufacturing of biogas require the digester to be heated. In order to maintain the ideal temperature for the bacteria to work. Moreover, pre-heating the feedstock before putting it in the digester can lower the amount of heat that is required. In order, to enhance the efficiency of this process. A common issue in the production plants is the need to heat large tanks of water. The static mixer ability of these devices has made them a preferred solution in many industrial processes.
Their efficiency is well regarded in water treatment plants as well as in the bio-fuel industry. The equipment having no moving parts makes it even easier to deal with.
More about digester heating with direct injection
What any company looks in equipment is the convenience of use and the maximum efficiency one could get with it.
Digester heating is an integral part of a number of processes. With direct injection steam heater, the process is simplified to a great extent. These come with threaded pipe connections for the steam inlet and have all sizes flanged connections.
So, how does it work? When you insert it into a tank filled with liquid. Generating a vacuum effect. By using the momentum of the steam leaving the scepter.
The liquid which surrounds the system is pulled into the equalizer. And with this; divided are the water and steam. Then combined by the elements of the equipment in the module chambers.
The process continues as they exit as co-rotating vortexes. Eventually, the steam comes into contact with the material. Without producing any noise or vibrations while being heated.
