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.

When a fuel defect occurs, the chemical energy of the fuel is not completely converted to heat, reducing combustion efficiency. This raises security concerns that unused fuel may ignite in the chimney and cause an explosion. Boilers must be adjusted to achieve complete combustion. One strategy to ensure complete combustion is to provide extra air. As shown below, a small amount of excess air increases the combustion efficiency, but a large amount reduces the efficiency.

Extra air is introduced into the burner to ensure complete combustion. But too much will cause the air to overheat and leak out of the boiler, reducing boiler efficiency and creating security problems. When the boiler is set, its purpose is to maximize combustion efficiency by providing extra air precisely and sufficiently for complete combustion, but not too much to reduce efficiency. How much extra air is needed to burn completely This rate varies in different designs and conditions of boiler and burner and different amounts of burner ignition but is usually between -%. Excess air must also adapt to fluctuations in temperature, density, and humidity of the boiler combustion air during the day and season. It is desirable to keep the amount of excess air constant throughout the ignition range.

Proper water hardening operations are essential to maintain the boiler operating properly. Each water hardening operation must be specifically planned and designed based on the minerals not dissolved in the compensating water, the percentage of distillation return, and the percentage of aeration. Insoluble solids in boiler water and water hardness in small and low-pressure motorhomes should be tested daily and in large and high-pressure motorhomes on an hourly basis. An annual inspection of boilers should include a thorough inspection and testing for signs of fouling or corrosion on surfaces adjacent to the water. The presence of even a thin layer of sediment prevents heat transfer and thereby reduces combustion efficiency. .

In commercial complexes, natural gas is mostly used as fuel for engine room boilers because it is usually easily accessible, clean, and more economical than diesel and electricity. Some engine boilers are designed to use more than one type of fuel (usually natural gas and diesel). Dual-burner boilers provide extra gas for fuel outages. It also allows the consumer to use petroleum fuel (diesel) when the amount of natural gas reaches a peak. When the amount of natural gas is higher than other fuels, it is possible to save on fuel costs by using cheaper fuel and limiting the use of natural gas.
