Hydrogen as fuel gas

 150 150 Alexander Hanf
By:

As a result of the energy transition, hydrogen is also becoming increasingly interesting as a fuel gas. Hydrogen/oxygen gas mixtures have been used in flame polishing of high-quality glass containers (crucibles, flacons, etc.) since a long time. LT has experience with engineering, safety design, production including control system, commissioning of systems for the supply of…

Mobile gas analyzer with two measurement cells

 1024 333 Alexander Hanf
By:

Transportable gas analyzers from LT GASETECHNIK can also be equipped with several measuring cells for mobile use at the customer’s request. For example with a thermal conductivity detector (short TCD with the typical use for forming gases, i.e. H2 in N2) and near infrared sensor (short NDIR with the typical use of welding gas CO2…

Natural gas mixtures, natural gas with hydrogen – gas mixing systems for test centers

 714 797 Alexander Hanf
By:

Gas mixtures of natural gas and hydrogen are very a hot topic. LT GASETECHNIK has been manufacturing systems for these applications for decades. Highly precise gas mixing systemscan reproducibly generate the required gas mixture composition with adapted measurement, control and analysis systems. These gas mixers are often used for test stands in test centers, laboratories…

If you use a gas mixer, choose a really accurate one, this will save (in a typical case) 30% of the Hydrogen costs!

 878 494 Stefanie
By:

The reason for this significant saving potential is a question of arithmetic: Here is an example: In this example the product quality will fluctuate and get worse if there are less than 5% H2 in N2 in the mixed shield gas.A conventional gas mixer has an accuracy of +/- 2% abs. that means for safety’s…

Safe lean-air supply of resin processes with – new article in the Asia Pacific Coatings Journal

 1024 199 Alexander Hanf
By:

The article in the February 2021 issue of APCJ describes the possibilities to meet the requirements of lean air system operators for quality, safety and availability. The aim is always to reliably maintain the specified oxygen concentration in the gas mixture to achieve defined product quality safely. The article describes various suitable technologies, including a…

Lean air gas mixer with SIL 1

Avoiding explosions with atmosphere control

 304 499 Alexander Hanf
By:

Explosive atmospheres in vessels are for example created by dust (ground products) or by degassing (production or storage of flammable substances). Covering with pure nitrogen can be undesirable. Either because the “lower explosion limit” can also be safely adhered to with a residual oxygen content or because a residual oxygen content is necessary in the…

Control system for 600 Nm³/h oxygen to supply a burner on a cement rotary kiln

Gas pressure control systems for burner supply

 1024 1024 Alexander Hanf
By:

LT GASETECHNIK has again manufactured and delivered two control and safety lines for the burner supply on a preheater tower of a German cement rotary kiln. The gas is used for afterburning nitrogen oxides (NOx) and carbon monoxide (CO) with propane/oxygen. Propane control and safety system: Performance: 3…30 Nm³/h Outlet pressure 4.2 barg Oxygen gas…

50 years LT GASETECHNIK

 1024 576 Juri Raffetseder
By:

LT GASETECHNIK, manufacturer of solutions for high-quality gas technology, is celebrating its 50th anniversary at the beginning of 2021. When Friedhelm Ludewig and Heinrich Tillmann founded a company in Dortmund-Barop in 1971, they probably had no idea what would become of LUDEWIG + TILLMANN oHG. Today we proudly look back on 50 successful years of…
