Furnace engineering | Factors You Require Considering For An Efficient Furnace

-




If you have an industrial furnace, then it is important to ensure its efficiency by reducing the overall maintenance costs while ensuring that the facilities will run smoothly without resulting in undue revenue loss. Keep on reading to know some of the tips for furnace engineering that make the furnace run efficiently.

Evaluate the furnace liner using IR thermography inspection
In IR thermography, is one of the crucial steps for evaluating the furnace lining quality. Moreover, lining quality is also important for protecting the steel from the heat as well as for limiting the heat loss from steel for enhancing the overall furnace efficiency.
In the scan, the IR camera is pointed at several points of the furnace casing to find out the outside temperature for analyzing the hot spots where there is heat leakage due to design issues. These are generally not visible by seeing from outside.

It can be greatly beneficial as the unit continues to operate. The IR camera can easily detect other problems and hot spots in the lining specialized engineers.

Based on the temperature, or depending on the difficulty in reaching a particular area, or seeing the size of the hot spot, one can carry out online repairs when required. Many of the maintenance engineers prefer online repair as this process is fast, reliable and economical. Ultimately, boilers generate revenue. Thus, it proves truly valuable if repairs are made when the unit is online. It also helps in avoiding revenue loss due to the faulty units. It also corrects the consequential losses due to the shutting down of the additional connected units.
 
By using traditional repair systems, it becomes important to shut down the furnace and cool these until it becomes safe for maintenance personnel to enter and repair the lining using pumpable, fibre blankets and monolithic.

Choosing the right material for rebuilds

In the case of IR scans, the area of concern is quite large for repairs. Moreover, the unit requires being shut down for the furnace relining or process heater relining. Finding the right material is the key to improving reliability and efficiency and for lowering the maintenance cost. The various factors to take into consideration include density, hardness, mechanical resistance, and the insulating factor. Based on the application of the furnace, one requires choosing a material with varying properties.

Understanding Condensing Boiler for Increased Efficiency

-

If you are looking for Condensing Boiler, then probably this is the best place where you can start from. A little information to brush up your knowledge is from 2005, it is mandatory for all gas-fired boilers to incorporate a condensing feature.   Now we begin with the basics as to what a condensing boiler is?  A condensing boiler is a heating appliance, especially water, which works using either gas or oil. It is designed with the objective of improving energy efficiency while it converts the condensing water vapors directly into heat for the building.  A condensing boiler is made on the same principles as that of non-condensing boilers as both of them have the same elements. The difference lies in the way the different amount of heat is produced using the burning fuel.   The efficiency of the boiler is calculated on the basis of its capability to alter the energy received from burning fuel into the one heating water circulating around the house.   How does a Cond

The furnaces are very important for winters, and we know it is very important for them to be in good condition. We must get the furnace checked properly before the winter begins. For all of us, it is essential that our furnaces should work from day to night to maintain a warm environment in the house. We have given some signs to look for in your furnace. All these signs indicate that it is the time to replace the furnace or call the specialized furnace engineering team for help.       Life of the furnace As per the rules, the average life of the furnace is at least 15 years. So, if your furnace is more than that, then it is time for you to change your furnace and get a new one for yourself. It is stated that the old furnaces consume a lot of electricity.       Weird noises Do you hear any strange noise from your home furnace, such as banging or squealing? The old furnace tends to make these noises when they are about to get damaged. So, if there is any such noise, then it

Importance of Boiler Commissioning and Maintenance Guidelines

-

Commissioning of a boiler is a systematic process initiated after erecting the machinery to make the boiler and its auxiliaries safe, steady, and secure for operation.  The plant owner must ensure that their boilers function securely and comply with their local and state building codes as well as all associated safety laws. Usually, the commissioning of new boiler equipment involves initial operative testing followed by the completion of the start-up trial. Once a boiler passes all tests and receives an operational certificate, it is regarded to be "commissioned." There are several steps involved in  boiler Commissioning  procedure; however, they might vary from place to place depending upon the regulations set by the governing authorities of the area in question. Broadly speaking, they should include the following standard procedures.  Test for Air leakage. Hydrostatic test. The process to test the aptness of Boiler auxiliaries. Gas
