Air Preheater

Rotary Heat Exchanger

For More Information:

Rotary regenerative air preheaters have a much reduced size and cost relative to recuperative tubular or plate heat exchangers.

Howden’s air preheaters are engineered to meet the demands of your application. We manufacture our air preheaters in modern facilities based around the world and produce bisector, trisector and quadsector arrangements. We can also provide packaged solutions in either vertical or horizontal alignment.

Our proven VN sealing system ensures that Howden heaters have minimal leakage and thus significantly reduce your operating costs. Other benefits of the VN design include a central drive system, advanced cleaning systems and enhanced maintainability.

Using specialised software we can model and accurately predict the operational and cost advantages of our proposals. Environmental considerations and energy costs make it more important than ever to ensure air preheaters are working at optimised levels.

Gas Gas Heater

Rotary Heat Exchanger

For More Information:

Howden supplied some of the world’s first FGD systems in 1934, and since then Howden has become a leading supplier of gas gas heaters.

The Howden VN design concept is ideally suited to the FGD Gas Gas Heater application. Judicious selection of materials, together with advanced design features result in a heat exchanger with exceptional resistance to the cool, moist acidic conditions of FGD plant, where fouling and corrosion are a constant challenge.

Gas gas heaters can be custom designed and optimised to suit arrangement and client preference. If the GGH is being mounted directly on top of the FGD Absorber, construction of the GGH at ground level and a single lift can reduce costs.

BASE

Steam Turbines

For More Information:

Howden Steam Turbine Base

The BASE steam turbine model is a compact solution for 75 – 1000 kW output range.

The steam turbine BASE is a generator drive specially designed for the 75-1000 kW output range. This favorably priced turbine features a simple, extremely compact design, short start-up times and a high degree of operational reliability. The BASE steam turbine is delivered as a pre-tested package unit with turbine, gear, generator, oil unit, control and protection unit as well as circuit breaker, built on a common base frame. The lightweight turbine package has a space requirement of approx. 1.5 m x 2.5 m x 2 m (width x length x height) and a weight of around 4,500 kg.

Design concept of BASE steam turbine series

The Base is a single-stage impulse turbine. The inlet steam flow is directed onto the turbine rotor blades, where mechanical power is generated when the steam flow direction changes. The resulting impulse spins the rotor, and the power is transferred from the turbine via the gear to the generator. The turbine casing is centrically slide-mounted on the bearing casing to permit free radial movements under influence of different temperatures. The vertical split allows easy access to the rotor disk.

This steam turbine is available for power generation applications and also as mechanical drives for pumps, compressors, and more.
