Outdoor Temperature Reset is a control strategy that continuously adjusts heating system supply water temperatures to compensate, providing more heat when it’s colder and less heat when it’s warmer. For most of the heating season, the control saves energy by operating at a lower temperature, reducing the amount of heat lost to the stack.
Design of an industrial boiler At full capacity a boiler of this size converts 3 000 litres of fuel oil or a corresponding amount of natural gas to thermal or process heat every hour.

They power package boilers, start up larger furnaces with fluidized beds and grates, and heat many other processes. Larger burners have Combustion Control Systems (CCSs) which should be tuned periodically. To understand how to tune a gas and/or oil (usually #2 Diesel oil) burner, it helps to first understand how and why they work the way they do.
Heating controls allow you to easily regulate the temperature of your home. The controls automatically turn the heating on and off based on settings input by the user, to ensure maximum comfort. This process moves away from a fixed, traditional timer system and can therefore be used to better control the temperature within your home.
Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.
There are basically two main types of feed systems : Open feed System; Closed feed system ; Open Feed System. A open feed system is found in a system with an auxiliary boiler, which is generally on a ship with a diesel engine. In an open feed system, steam from various systems comes to the condenser and gets converted into water.

Jan 07, 2003 · Multiple boiler systems should be piped and controlled so flow through the boiler is limited to times when the boiler is firing (or is in a thermal pre-purge or post-purge mode). The preferred arrangement, especially when condensing boilers are used, is to pipe each boiler in parallel with the other, as shown in Figure 1.

Combustion Air 1. Determine the ambient air conditions in the boiler area and determine current fresh air supply (e.g., louvre area).
In a hot water gravity heating system the circulation of water is a result of the density difference between hot water in the supply lines and cold water in the return lines. The hot water tends to flow upwards and cold water tends to flow downwards. The elevation of the supply and return lines are therefore important for proper functionality.
