All combustion equipment must be operated properly to prevent hazardous conditions, catastrophic damage, and human and construction damage. The main reason for the explosion of engine room boilers is the combustion of flammable gases that have accumulated inside the engine room boilers. This can happen for a variety of reasons, such as fuel, air, or the combustion process is interrupted for any reason, the flame goes out, and flammable gases accumulate that cause re-burning.

Symptoms of incomplete fuel include smoke, yellow flame, flame extinguishing and soot and blackened boiler pipes. To ensure the optimization of the combustion process, it is better to adjust the engine of the engine room boilers annually. In a boiler that uses natural gas, usually, about % of the extra air is suitable to ensure complete combustion and achieve maximum efficiency, which corresponds to to % of excess oxygen. Activation with more than % excess air is not desirable and may reduce efficiency and further diffusion. Therefore, it is preferable to keep the amount of excess air in the desired range throughout the ignition range. The desired limit can be achieved by using burner controls, which include parallel placement of controls, cross-limiting controls, and oxygen conduction controls. These types of controls are better options than traditional mechanical jackshaft controls. The following is a brief description of the types of burner controls:

This type of pot or boiler is made up of connecting cast iron pieces called fins. Due to the ability to assemble and disassemble the cast iron boiler, it can be used in spaces where it is not possible to use a steel and integrated boiler. In fact, cast iron boilers are assembled and installed in the engine room. types of sections are used in the construction of each capacity of cast iron boilers, which are as follows.

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. .

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.
