Flues Sentence Examples

The farther ends of the flues of several such kilns are connected with a chimney shaft.

To prevent the atmosphere from becoming unduly dry a pan of water is fitted to the stove; this serves to moisten the air before it passes into the distributing flues.

In flue curing, also known as the Virginian cure, fires are set outside the barn; and the heat led in iron pipes or flues, into the building are under the suspended tobacco, which is placed there quite fresh from the field.

In many mints the flues pass into condensing chambers where volatilized gold and silver are recovered.

Beyond this we often find the calefactorium or day-room - an apartment warmed by flues beneath the pavement, where the brethren, half frozen during the night offices, betook themselves after the conclusion of lauds, to gain a little warmth, grease their sandals and get themselves ready for the work of the day.

Plant houses were formerly heated in a variety of ways - by fermenting organic matter, such as dung, by smoke flues, by steam and by hot water circulating in iron pipes.

It is set to span the furnace, additional exposure to heat being secured in a variety of ways by flues.

Exposure in the conical boiler is direct on its inner surface, and is supplemented by flues.

It involves the keeping clean of flues, ashpits and especially the fires themselves.

Another plan in the greenhouse is to dash water on the pipes or flues, which causes steam to rise to the glass and freeze there, stopping up all the crevices.

Traces of thallium, which are present in some pyrites, may be detected in the flues of the furnaces where the metal is roasted.

This is dug out, and after being dried on floors heated by flues is ready for burning.

The buildings in which this process is carried out are built of stone and are divided into compartments heated by means of hot air derived from a system of stoves and flues.

It is important in all fire-proofing of columns and girders, and in all floor construction, furring and partitions, that there shall be no continuous voids, either vertical or horizontal, which may possibly serve as flues for the spread of heat or flame in case of fire.

The gas-producers constructed by Messrs Siemens Brothers, from 1856 onwards, were provided with a kind of brick chimney; on the top of this there was a horizontal iron tube, continued into an iron down-draught, and only from this the underground flues were started which sent the gas into the single furnaces.

The retort E is charged with ordinary bituminous coal which is submitted to destructive distillation by the heat communicated through the flues n 2 n 2, and is thus converted into coke.

The hot producer-gas formed in V is passed round the retort E in the flues n 2 n2, and ultimately goes away through K to the furnace FIG.

The lateral flues c, c prevent the brickwork from being melted.

The former are used principally as casing, walls, pillars or other supporting parts of the structure, and includes ordinary red or yellow bricks, clay-slate, granite and most building stones; the latter are reserved for the parts immediately in contact with the fuel and flame, such as the lining of the fire-place, the arches, roof and flues, the lower part if not the whole of the chimney lining in reverberatory furnaces, and the whole of the internal walls of blast furnaces.

In an oxidizing atmosphere it is indifferent to silica, and therefore siliceous bricks containing a considerable proportion of ferric oxide, when used in flues of boilers, brewers' coppers, &c. and similar situations, are perfectly fire-resisting so long as the heated gas contains a large proportion of unconsumed air.

Even under the most advantageous application, that of evaporation of water in a steam boiler where the gases of the fire have to travel through a great length of flues bounded by thin iron surfaces of great heat-absorbing capacity, the temperature of the current at the chimney is generally much above that required to maintain an active draught in the fireplace; and other tubes containing water, often in considerable numbers, forming the so-called fuel economizers, may often be interposed between the boiler and the chimney with marked advantage as regards saving of fuel.

In reverberatory and air furnaces used in the different operations of iron manufacture, where an extremely high temperature has to be maintained in spaces of comparatively small extent, such as the beds of puddling, welding and steel-melting furnaces, the temperature of the exhaust gases is exceedingly high, and if allowed to pass directly into the chimney they appear as a great body of flame at the top. It is now general to save a portion of this heat by passing the flame through flues of steam boilers, air-heating apparatus, or both - so that the steam required for the necessary operations of the forge and heated blast for the furnace itself may be obtained without further expenditure of fuel.

Small air-furnaces with hot plates or sand bath flues were formerly much employed in chemical laboratories, as well as small blast furnaces for crucibles heated with charcoal or coke.

I had to get up at half past five twice a week to clean the flues out.

Good Practice You should keep detailed records of any maintenance work carried out on the gas pipe work, appliances and/or flues.

Of these features, the blast-pipe had been employed by Trevithick on his engine of 1804, and direct driving, without intermediate gearing, had been adopted in several previous engines; but the use of a number (25) of small tubes in place of one or two large flues was an innovation which in conjunction with the blast-pipe contributed greatly to the efficiency of the engine.

In some cases, especially in dry distillations, the furnace flames play directly on the retorts, in others, such as in the case of nitric acid, the whole still comes under the action of the furnace gases to prevent condensation on the upper part of the still, while in others the furnace gases do not play directly on the base or upper portion of the still but are conducted around it by a system of flues (see Coal-Tar).

Split flues were utilized in the fireplaces to accommodate windows above the mantels.

Other sources include wood-burning stoves, kerosene heaters, improperly ventilated water heaters and gas stoves, and blocked or poorly maintained chimney flues.
