Jan 04, 2021· The starting point for the distribution system is the boiler house, where it is often convenient for the boiler steam lines to converge at a steam manifold usually referred to as the main distribution header. The size of the header will depend upon the number and size of boilers and the design of the distribution system.

Pipe Sizing Steam Supply andCondensateReturn Lines

Pipe Sizing Steam Supply and Condensate Return Lines Definitions Steam mains or mains carry steam from the boiler to an area in which multiple steam-using units are installed. Steam branch lines take steam from steam main to steam-heated unit. Trap discharge lines move condensate and flash steam from the trap to a return line.

Dec 05, 2017· Sizing a Steam Boiler. December 5, 2017. By Ron Beck, U.S. Boiler Company. Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once that’s been determined, you can accurately select a boiler

A general rule of thumb is that 1 psi of steam will raise water about 2 feet. For example, a 5 psi system should not have condensate lines higher than 10 feet above the steam trap. Properly Size Steam Trap Drip Leg Lines. Not only must steam traps be piped off the bottom of the steam lines, the pipe must be properly sized.

Steam lines should be arranged to fall in the direction of flow, at not less than 100 mm per 10 metres of pipe (1:100). Steam lines rising in the direction of flow should slope at not less than 250 mm per 10 metres of pipe (1:40). Steam lines should be drained at regular intervals of 30-50 m and at any low points in the system.

My suggestion is to size the headers so that the flow velocity within them does not exceed two feet per second when carrying their maximum flow rate. This piping layout eliminates the “ghost flow” and possible recirculation issues previously described. It also provides equal supply temperatures to each of the load circuits.

On some boilers there can be a 5 to 10 times factor for the pump size compared with the burn rate. A simple solution is to do away with the boiler’s onboard pumps and increase the supply pressure from the transfer pumps. This arrangement will eliminate the cost and electrical load of the boiler mounted pumps, reduce the

The smaller temperature drop of the two-pipe system helps keep the temperature of the water returning to the boiler above the dewpoint of the exhaust gases, thus preventing flue-gas condensation. Two-pipe systems are the best choice for use with low-temperature heat sources such as heat pumps or condensing boilers.
