Increased boiler efficiency is one of the simplest methods for a business to cut operating costs and get a good hand over boiler controls. Examining how recently you completed boiler maintenance and how efficient your boiler is is an excellent place to start minimizing your bills.
We need to understand boiler efficiency before we can discuss efficiency tips. The stack or boiler water is where the majority of heat is lost in your boiler.
The goal is to create conditions that produce the least amount of flue gas at the lowest temperature achievable. As a result, the boiler’s efficiency improves.
Consider this: the boiler takes in cool air, heats it up, and then exhausts it through the stack. Because the greater the temperature, the more energy escapes with the flue gas, a lower stack gas temperature is ideal. The boiler system, on the other hand, takes in cold water, heats it to steam, and then uses it.
Get your skills ready to make a good difference in boiler controls meanwhile below-mentioned points will help you to increase boiler efficiency:
- Lower the stack temperature to increase boiler efficiency:
A simple day/night setback could help lower stack temperatures. When resting at night or on mild days, this lessens the operating pressure in regards to steam boilers and the operating temperature for hydronic boilers.
- Economizer Installation:
Hot flue gas which is discarded is utilized to warm/heat the feed water on its way to the boiler. This should be your first priority if your economizer isn’t operating. Economizers conserve fuel and protect the boiler from the harmful effects of cold water supply.
- Tune the burner regularly:
examine the boiler’s waterside and clean out any mud legs or drums. When it comes to boiler efficiency, another common issue is not getting the proper amount of air. A particular amount of oxygen is required for proper fuel combustion inside the boiler. If there isn’t enough air, the carbon in the fuel will be oxidized, resulting in carbon monoxide.
Because the fuel isn’t entirely burned, less heat is released, lowering fuel use efficiency. Soot, smoke, and carbon monoxide are all harmful byproducts of low air. In addition, too much air affects efficiency. The excess air enters the stack cold and exits hot, losing heat.
The ideal procedure allows the fuel to burn safely with just enough air.
An O2 probe is used to determine the amount of air required. While tuning the burner for maximum boiler efficiency, we insert the probe into the stack.
- Clean the side of the fireplace:
Soot may accumulate on the fireside of the boiler tubes over time, especially with older equipment. This soot coating works as an insulator, slowing heat transfer and increasing fuel consumption. Due to the lower heat transfer rate, the hot gases go through without transferring heat which in turn raises the temperature of your stack.
As part of your routine boiler maintenance, clean and inspect your boiler tubes to ensure that soot is kept to a minimum. This improves the boiler’s overall efficiency.
