Increasing the Energy Efficiency of Boiler and Heater

Example: If only 10 flanges are not insulated on a 10-cm (4-in. diameter) pipe carrying steam at 860 kPa (125 psig), the annual heat loss is equivalent to 2450 m 3 of natural gas (worth $370). Example: A 3-m (10-ft.) length of uninsulated 10-cm (4-in.) steam pipe wastes more than twice as much money in steam costs per year than the cost of

FUNCTION 4(2) boilers - AK Ramanujan

The boiler construction rules do not allow studs to be fitted around the opening and hence this design. The loss of tightening efficiency is made up by fitting an asbestos cloth joint of sufficient thickness to take up any uneven pressure resulting in uneven thickness all round so preventing leakage of steam.

Vessel manways, handholes pose special sealing challenges

Some use standard ASME-type flanges and are bolted much like flanged pipe connections. Internal manways and handholes have covers or plates that fit inside a vessel and are drawn back against a gasket and external flange. These designs pose a number of sealing challenges. For example, flange surfaces are often less than perfect.

What is Steam Locomotive? | RayHaber | raillynews

A "check valve" (one-way valve) kept the steam inside the boiler. The dry steam was either taken from the top of the boiler and collected in a perforated pipe or from a point at the top of the boiler and collected in the steam droplet. This dry steam was then transferred to a regulator and the regulator controlled the distribution of the dry steam.

Flange - Wikipedia

A flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel.Thus flanged wheels are wheels with a flange on one side to keep the wheels from running

Simple Boiler Design - Steve's workshop

Atop the boiler were two bushes, one for a safety valve and the other for a steam take-off point. An optional feature was the water level plug on the front end plate. This was not a necessity, but would make filling the boiler to the correct level easier, particularly when starting with an unknown quantity of water inside.


BOILER ROOM PIPING. In the design of a steam plant, the piping system should receive the most careful consideration. Aside from the constructive details, good practice in which is fairly well established, the important factors are the size of the piping to be employed and the methods utilized in avoiding difficulties from the presence in the system of water of condensation and the means

What causes arcing at steam fitting? | EC&M

Q We recently installed a new steam pressure reducing station in an existing 6-m. 150-lb steam line. After reinsulation of the pipe with foil-jacketed, 2-in.-thick fiber glass, electrical arcing started between the new insulation foil jacket and the steel strainer [ILLUSTRATION FOR FIGURE OMITTED]. The spark jumps a gap up 1/2 in. To date, we have been unable to find a logical reason for the


(3.) Fit a steam gage, so that you may know what is happening. (4.) Test your boiler under steam, and don't work it at more than half the pressure to which it has been tested. (See p. 220.) In the present chapter we will assume that the barrels of all the boilers described are made out of solid-drawn seamless copper
