To increase the overall efficiency of the boiler, the heat released from the combustion process must be properly transferred into the fluid used. Any heat that is not transferred to the fluid is lost through the body of the boiler or the flue gas. The temperature of the gas inside the chimney is a good indicator of the heat transfer process and therefore efficiency. There are practical limitations to the low flue temperature. Its temperature will be higher than the fluid used in the boiler. In boilers that do not do distillation, the temperature should be high enough that water vapor does not distill in the exhaust chimney and clean the heat transfer surface in the distillation that causes corrosion. Condensing boilers that use natural gas are made and designed with accessories that are resistant to corrosion. Also, their chimney temperature can be less than . degrees Celsius. Trapping heat distillation increases efficiency by more than %.

Eng. Shamel, I wanted to thank you and CATEC team as well for taking time from your busy schedule to support and help Americana meat KSA on all utilities projects (steam boilers, thermal oil heaters, etc). I kNow some of the work wasn’t part of your normal responsibilities, but your assistance was invaluable in helping my company get everything done in a very timely manner. Your expertise and enthusiasm were both appreciated during a time which can be stressful for all concerned! We sincerely appreciate your efforts and thank all CATEC team

Figure shows the combustion efficiency chart for natural gas fuel with electricity, which shows the relationship between excess air and flue gas temperature with combustion efficiency. For example, by following the Step line in the diagram, the amount of oxygen at % in the flue gas (as shown in the diagram equals approximately % of the excess air) and ° F as the flue gas temperature rises, the corresponding combustion efficiency is about . % is observed. At the same increase in the flue gas temperature by degrees Fahrenheit, the Step line shows that reducing the oxygen in the flue gas to % increases the combustion efficiency to about .%. The lower the percentage of oxygen in the flue gas, the less heat is transferred to the excess oxygen, resulting in increased fuel efficiency. The higher the efficiency, the more heat will be transferred to the inlet water instead of to the flue gas, thus reducing the flue gas temperature.

The pressure difference between the combustion chamber of the boiler and the ventilator (also called the exhaust chimney) creates a suction that carries the products of combustion along with the boiler and directs it to the chimney. The natural suction of boilers depends on the natural buoyancy of hot gases to remove combustion products through the aerator and direct fresh air into the combustion chamber. Mechanical suction of engine room boilers includes compressed air, where the air is forced into the combustion chamber by a fan or blower to maintain positive pressure. Induction suction, where the air is drawn through the combustion chamber by a fan or blower to maintain negative pressure.

Introducing the types of engine room boilers, advantages and disadvantages and the best maintenance methods: With the proliferation of day-to-day activities digitally, such as renting property or purchasing equipment, building painting other services that were commonplace on a daily basis and were mostly done in person have generally shifted to E-learning, such as contracting services. Home, etc., but in this way, problems have also involved people and businesses due to this change. Guaranteeing the performance of work by the contractor to provide services or goods, as well as guaranteeing the payment of remuneration by the employer are some of the most important of these challenges. In recent years, the development of blockchain technology among technology enthusiasts, as well as the implementation of
