If your building has several boilers, you need to estimate whether you really need to put the boilers in standby mode (at pressure and temperature), as this will waste energy. The stand-by boiler not only interrupts the cycle but also releases heat to the surrounding environment during the loss of radiation, which significantly increases the boiler input power while reducing ignition. Give. At low ignition values, for example, when the boiler is maintained in standby mode, the efficiency drop can reach %. Maintaining the standby state of the boiler will cause a quick recovery in case of failure of the previous boiler, but this action must be measured by the huge and useless consumption of energy. If you do not need a boiler in standby mode in your activity or you only need it in certain seasons, you must turn off all the boilers that you do not need to prevent energy loss.

Cast iron boilers are very useful because they can be collected in the basement and passed through smaller doors and gates. The most important drawback is that they are prone to leakage due to the connection of the parts by the washer when the washer becomes old or damaged by chemical reactions. Among the famous cast iron boilers in Iran, we can mention the boiler cast iron boiler and M.I. cast iron boiler made by Iran Pipe and Machine Building Company.

In commercial complexes, the boiler is very different in summer and winter, night and day, working days and weekends. Using a boiler can not apply this load difference well. When the heat generated by the boiler at the lowest ignition rate exceeds the heat required by the building, the boiler cycle will be interrupted. Starting and interrupting the cycle in the boiler is not efficient at all because, in each cycle, a pre-combustion discharge and a post-combustion discharge are performed to direct the heat out of the boiler. Also in the case of boilers that do not perform the adjustment operation, when the combustion efficiency is at its best, the cycle process does not allow the boiler to operate in the second boiler and the ignition rate is constant.

The presence of large amounts of accumulation of insoluble solids (TDS) in the boiler water can cause sedimentation and reduce the efficiency of the boiler. Therefore, it is necessary to keep the number of solids below the specified limit. As the total hardness increases, the likelihood of sedimentation and sedimentation increases. Drainage of water, called pot immersion, requires the removal of some of the undissolved solids and keeping the total hardness below the rate at which it precipitates. Low but constant and frequent submergence of high doses but rarely is better because it preserves energy, water, and chemicals. Large boilers with a constant load must be continuously submerged where small amounts of water are constantly drawn from the boiler and fresh compensation water is produced.

The hot water produced by the boiler is pumped through pipes and reaches the building equipment, which can include hot water coils in the fan coils, hot water heating equipment and heating systems. Boilers produce steam that flows from high-pressure to low-pressure areas through pipes without the need for an external energy source, such as a pump. The steam used for heating can be used directly for steam-powered equipment, or through a heat exchanger can generate heat to produce hot water for the equipment.
