Typical ultrasonic nozzles offer significant advantages: they do not block even during long-term operation and are suitable for highly viscous and contaminated liquids. They have a control range of up to 1:10 as well as an extended service life - due to the low speed and low pressure in the liquid supply. In addition, they are characterised by a fine, humogenic droplet distribution.
Advantages of ultrasonic nozzles:
- Stable and quiet spray pattern, uniform atomisation
- No moving parts
- Production in different materials
- Less abrasion
- Extended control range
- Use of different distributors
- Tulip and jet atomisation with only one basic body
- simple conversion from tulip to jet nozzle during commissioning
- economical use of atomising medium reduces costs
As a result of several customer requests, CS Combustion Solutions has developed a unique nozzle that combines all the advantages of a typical ultrasonic nozzle with a significantly reduced atomiser requirement of approximately 50%. JULIP has enormous potential - reducing operating costs while improving the efficiency of thermal oxidation and sulphuric acid production plants.
The VARIEX lance was specially developed for the combustion of explosive gases. Due to the patented design of the lance, a constant outlet speed of the gas from the lance can be guaranteed over the entire control range.
Through axial adjustment of the conical body at the lance outlet into the combustion chamber, with the aid of a pneumatic actuator, the geometry of the lance is adapted to the respective gas flow rate, so that the outflow speed from the annular gap is always greater than the backfire speed of the gas.
Due to this design, even a strongly varying gas flow can be controlled without adding inert gas. The VARIEX lance is considered a mechanical backfire protection device in the sense of TRBS 2151 and can therefore be used as an additional measure to reduce the risk of explosion.
Like every CS fuel lance, the VARIEX lance is available in different sizes, material configurations and different approvals (PED, ATEX,...).
In order to survive economically in a competitive market, plant operators are increasingly faced with the challenge of achieving higher output rates with existing combustion systems. The situation is made more difficult by special low-calorific by-products that oxidise the combustion air through the use of additional booster fuels. Increased flue gas volumes reduce the residence and burnout times or increase the pressure loss of the flue gas. The operator also struggles with poor part-load performance associated with poorly mixed gases and CO strings resulting from the combustion of residues of increasingly variable quality. Conventional air burners do not have the extreme flexibility necessary to solve these problems.
CS has worked with customers and partners to develop solutions that can deal with these difficult conditions.
This burner works with oxygen instead of air.
After commissioning with a support fuel such as natural gas or heating oil, this burner works with almost any combustible fuel. This process can be retrofitted without having to install a new burner block in the existing combustion chamber. With the special PreCOMB muffle system, it is possible to run additional fuel vapours.
