Four huge natural draught cooling towers cool the station's circulating water.

Most boilers now depend on mechanical draft equipment rather than natural draught.

The towers were 88 metres in height and used the natural draught hyperboloid design.

They were fitted with economisers and natural draught, working at a pressure of 160 psi.

They were small shaft furnaces using induced natural draught.

The Catalan forges can also be built bigger than natural draught bloomeries.

Flue products are removed by natural draught vertically to atmosphere, through a suitable terminal.

The design included Queensland's first hyperbolic natural draught cooling towers which rise to 118 m.

Instead of using natural draught, air was pumped in by a trompe, resulting in better quality iron and an increased capacity.

Blowtorches are typically a single hand-held unit, with their draught supplied by a natural draught of air.

At both Vijaydurg and Dahanu, there is natural draught of 20 metres to receive bigger ships.

The pieces were part of the furnace wall, the holes designed to allow a natural draught of air to pass through evenly into the furnace.

A fan-assisted flue may be noisier than a natural draught flue but is more efficient and can result in greater fuel efficiency.

These pipes, called tuyères, allow air to enter the furnace, either by natural draught, or forced with bellows or a trompe.

This is because natural draught is subject to outside air conditions and temperature of flue gases leaving the furnace, as well as chimney height.

Boilers to supply the steam engine are housed in a single-storey boilerhouse alongside the main brewhouse, usually with a prominent chimney to provide natural draught.

Fan assisted natural draught - A hybrid type that appears like a natural draft setup, though airflow is assisted by a fan.

More extensive guidance is given for both fanned and natural draught appliances on safely distancing flue outlets from openings in buildings and combustible elements.

Natural draught through the use of a chimney is a type of induced draught; mechanical draught can be induced, forced or balanced.

It was also considered the Installation Code NZS5261:1996 lacks guidance on determining minimum flue heights for domestic natural draught appliances.

That movement or flow of combustion air and flue gas is called "natural draught/draft", "natural ventilation", "chimney effect", or "stack effect".

The output coolant achieves 36 C and is therefore transferred to the 150 m tall natural draught wet-type cooling tower that returns it to the initial temperature.

Designing chimneys and stacks to provide the correct amount of natural draught or draft involves a number of design factors, many of which require iterative trial-and-error methods.

Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two main reasons.

As the furnace relied on natural draught, a tall chimney was required at the far end of the flue to encourage a good supply of air (oxygen) to the fire.

His hair was moving a little in the natural draft through the room.

It is at this temperature, then, that the lowest natural draft will occur.

By April 1978 one natural draft cooling tower had been built, and a second was under construction.

Our traditional smoker does not rely on the forced air process but the natural draft effect.

Some fuel-burning industrial equipment does not rely upon natural draft.

In fact, it's easier to control and more versatile than any natural draft smoker ever built.

The plant has a 520-foot natural draft cooling tower.

Performance evaluation of natural draft based agricultural residues charcoal system.

Provides greater draft than natural draft systems can economically offer.

These boilers were natural draft and exhausted into two large chimneys.

The natural draft carried the smoke into the cavern.

The first category would be natural draft, atmospheric burner furnaces.

The water was cooled using four hyperboloid natural draft cooling towers.

Oxidisers can, however, be designed for natural draft operation under special circumstances and are sometimes used in oil refineries.

These units are cooled by natural draft cooling towers.

Galaxy is one of Canada's most efficient and best built natural draft cast-iron boilers.

The teams are divided into two groups on the basis of their natural draft order from the previous rookie draft.

If the exhaust vent does not have vertical sections to provide natural draft, smoke may spill into the home (Figure 14).

Its low profile and high efficiency natural draft design make Sentry ideal as a replacement or for new installations.

The stacks (or chimneys) provide sufficient natural draft to meet the low draft loss needs.

It is possible to locate a fan forced cooling system closer to the turbine than a natural draft system.

Natural draft - Utilizes buoyancy via a tall chimney.

Drifting upward on a natural draft.

Burnham is a reliable "natural draft" boiler, achieving high efficiency with fewer components.

Designing chimneys and stacks to provide the correct amount of natural draft involves a great many factors such as:
