As mentioned earlier, any type of waste, such as soot or sediment, that covers the boiler heat transfer surface will reduce efficiency and increase the likelihood of parts and equipment failure. Cleaning of this surface is necessary according to the manufacturer&#;s recommendations for the life of the equipment and to maintain the optimal performance of the boiler. The waste that covers the boiler pipes prevents heat transfer and raises the temperature of the aerator gas. If incomplete combustion occurs, the resulting soot will accumulate in the part of the pipe where combustion has taken place. Similarly, inadequate water treatment in the water sections of the pipes causes sediment to accumulate in these sections. Only a .-inch-thick layer of soot or sediment can reduce heat transfer by up to . percent, and a .-inch-thick layer by percent.

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.

Modular boilers are small in size and capacity and are usually used to replace several small boilers instead of one large boiler. These modular boilers pass through standard ports and are portable through stairs and elevators. These devices can be arranged in different order to make the most of small places or embed other equipment in those places. These boilers can efficiently provide the required heating load.

In facilities, in addition to limiting, the system activity sequence is also important to achieve energy efficiency. Nowadays, with the general use of VAV (variable volume) systems in commercial complexes, simultaneous heating and cooling and overheating of the primary air are often ignored. Applying boiler restrictions based on outside air temperature, for example when the temperature is above . degrees Celsius, is an effective way to prevent this situation.

Security control of engine room boilers includes high temperature and pressure, high and low gas/diesel pressure, high and low water level, and control of flame safety measures. These controls take into account the safety and limitations that cause the electrical circuit to crack to prevent engine boilers from catching fire. For example, when the boiler pressure exceeds the set range, the fuel valve closes to avoid the dangers of high pressure. Security issues in the flame control system include keys for water shut-off, high restrictions, air stability keys, executive control, and flame sensor. The flame sensor often includes ultraviolet and infrared rods and sensors that are used to indicate the flame status and deactivate the burner in unsafe and unsafe conditions where no combustion has taken place. The flame safety control is set to start and cycle during the execution steps.
