This steam condensing adds to the water in the pipe and naturally causes an overflow, which is led back to the boiler and re-used. 2 For large public buildings, factories, &c., heating by steam is generally adopted on account of the rapidity with which heat is available, and the great distance from the boiler at which warming is effected.

Jun 18, 2014 · There sure is a lot of water in those systems, and that 1.15 pick-up factor isn't going to be enough to take on all that extra water. And this is why boiler manufacturers are pushing primary-secondary pumping and boiler-bypass piping these days. Without one or the other, that new boiler you installed will probably never shut off.
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Hi. While I'm waiting for quotes to come in from the contractors, I'm wondering whether it's better to undersize or oversize a boiler when your EDR falls between two sizes. Let's say I have 420 square feet of radiation. That puts me smack in the middle of the Peerless ...

The sulfate ion is a polyatomic anion with the empirical formula SO42- and a molecular mass of 96. 06 daltons; it consists of one central sulfur atom surrounded by four equivalent oxygen atoms in a tetrahedral arrangement. The sulfate ion carries a negative two charge and is the conjugate base of the hydrogen sulfate ion, HSO4-, which is the conjugate base of H2SO4, sulfuric acid.

In the larger stills (55 mm.) a series of thin glass lining tubes, eachl 7.5 cm.
Again, if we supply our boiler with this condensing water of the temperature of 160 degrees, it will lower the temperature in the boiler perhaps 30 degrees, from 310 to 280 degrees, and by that means reduce the elastic power of the steam from 120 to 60 pounds, (see the scale, article 3.) which would be losing 22.4 pounds, the average of 60 ...

He next applied a pump to extract the injection water, the condensed steam, and the air, from the condensing vessel, every stroke of the engine. To prevent the cooling of the cylinder by the contact of the external air, he surrounded it with a case containing steam, which he again protected by a covering of matters which conduct heat slowly.
On the top part or any other convenient place of the vessel, are fixed two cylinders or tubes of a proportional size to the cylinders on the wheel, one of which is a condensing cylinder, by means of a screw and piston, and by which the water in the vessel may be compressed; the other has its piston suspended at the bottom, and the top part of ...
Principals of Condensing Boiler System Design Dennis Jones, P.E. Member ASHRAE ABSTRACT Condensing boilers can provide significant energy savings due to operating efficiencies as high as 98% as compared to a peak efficiency of 80% for a conventional boiler.

The Moline system is styled the Vacuo Vapor Method, and in the method of piping is quite similar to other vacuum systems—that is, in so far as the steam supply and air-line are concerned. The air and steam in the air-line are taken to a condensing radiator; and an ejector placed between the supply valve and the radiator creates the necessary ...

While milk is a staple and nutritious drink today, at the time it was risky to consume. Cow milk was ridden with bacteria, and if it wasn’t consumed within several hours in the summer, it spoiled in the heat, causing milk poison or milk sickness.
STEAM ENGINE. r. A steam engine. is a machine for the conversion of heat into mechanical work, in which the working substance is water and water vapour. The working substance may be regarded from two points of view. Thermodynamically it is the vehicle by which heat is conveyed to and through the engine from the hot source (the furnace and boiler).
Having thus described our invention, what we 2 claim as new and desire to secure by Letters Patent is: 1. A method of testing the purity of steam which comprises condensing the steam, causing the condensate to flow between electrodes, maintaining the condensate in vacuo and testing the condensate by measuring its electrical conductivity. 2.
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.

A condensing steam locomotive is a type of locomotive designed to recover exhaust steam, either in order to improve range between taking on boiler water, or to reduce emission of steam inside enclosed spaces. The apparatus takes the exhaust steam that would normally be used to produce a draft for the firebox, and routes it through a heat exchanger, into the boiler water tanks.

This is obtained by rapid cooling and "seeding" with finely powdered lactose or old condensed milk at a temperature of about 85oF. Condensing is the only type of manufacture the dairy industry in which "trade secrets" are maintained and the art of condensing depends mainly on the control of cooling and seeding.
