Follow our increase in boiler efficiency tips to get the best performance from your boiler. Increasing the efficiency of the boiler greatly improves the overall efficiency. Increasing the efficiency of the boiler can also save energy and cost. One of the simplest ways to reduce the operating costs of a business is to use energy-efficient equipment. A good opportunity to start reducing your bills is to look at how your boilers have been serviced and how your current boiler works effectively.

increase boiler efficiency

Most of the heat from your boiler is wasted in the boiler or boiler water. The goal is to create conditions that produce the smallest amount of flue gas at the lowest possible temperature. This increases the efficiency of the boiler. Our goal is to increase boiler efficiency. You know the boiler works in the cold, heats it and sends it out to the chimney. The low temperature of the flue gas is ideal because, at higher temperatures, more energy is transferred through the flue gas. On the other hand, the boiler system works with cold water, using heat to convert it to steam. Wherever we lose heat, steam, liquid or hot water, we lose valuable energy.

Lower the chimney temperature.

One way to increase the efficiency of the boiler is to reduce the chimney temperature. This may be as simple as adjusting the night or daytime pressure drop on the boiler or operating the hydraulic boiler during shutdown or on fall and spring days.Install an economizer to increase boiler efficiency.

Install an economizer to increase boiler efficiency.

An economizer uses the wasted heat of the flue gas in another way to heat the boiler inlet water. If your boiler does not have an economizer or your economizer is not working, this should be a top priority. The economizer saves fuel consumption and reduces the potentially harmful effects of boiler cold water supply.

Regularly set the torch to increase boiler efficiency.

Regularly check the water and remove the sludge. Other common issues occur when the boiler does not receive the right amount of air. A certain amount of oxygen is required for proper combustion of fuel inside the boiler. If the air is low, the carbon in the fuel will be completely oxidized and carbon monoxide produced. This causes less heat to be released because the fuel is completely unburned, which reduces fuel efficiency. It produces low air, smoke and carbon monoxide, all of which are very dangerous. Excessive air also reduces boiler efficiency. Excess air will lower the temperature and heat will be lost through the chimney. So keep that in mind for increased boiler efficiency.

An optimum process provides just enough air to burn easily. In some equipment, the temperature of the air drawn to the burner varies with the seasons and requires a higher burner setting for maximum savings.

Insulate your valves.

Many factories avoid insulating the valve in the boiler room and will never turn it back on because it is difficult. This can reduce performance rather than Boiler efficiency increases.
However, exposing these large valves can cause the heat loss and heat the boiler room unbearably, even with low gas prices, insulating these valves with a blanket can Significantly save money, improve the comfort of the boiler room, reduce the risk of burns, while also allowing easy access to maintenance.

Exterior wall pipe cleaning and increase boiler efficiency substantially

Over time, some of the soot boiler pipes may develop, especially with older equipment. This soot layer acts as an insulator, reducing heat transfer rate and increasing fuel consumption. Because of the low heat transfer rate, hot gases pass through the water without heat transfer and increase the chimney temperature. Cleaning and checking boiler pipes as part of regular boiler maintenance ensure that soot remains low and improves overall boiler efficiency.Install an economizer to increase boiler efficiency.

The effect of combustion preheating on Boiler efficiency increases

The burner must heat the incoming combustion air with a flame. If the inlet air to the burner is warmer, the burner needs less fuel to generate the same amount of steam in the boiler. Increasing the average 3 degrees Fahrenheit in fresh air temperatures can save 2 percent on fuel costs. If you run big boilers all day long, it can really raise even the historically low gas prices. In some cases, an air preheater can cost less than a year.

Clean the water pipes

Keeping the boiler tubes clean and leak-free requires hard water correction. To ensure a good heat transfer from the metal to the water, regularly check your water and remove any sludge. There is no doubt that cleaning the pipes has an effect on the increase in boiler efficiency. If the boiler water hardness is too high or improperly modified or the boiler is not drained regularly, a layer will accumulate on the thermal transfer surfaces. This layer will prevent heat transfer and reduce the efficiency of your boiler. This layer also prevents water from cooling the heat transfer surfaces. If left unattended, this layer can overheat the boiler, resulting in costly repairs and leaks to the boiler.

Return condensate to the boiler

The condensate is formed as the steam conveys its heat and condenses. It is unacceptable to dispose of these byproducts because clean water is free of solids or gases that are ready for use in the boiler itself. The water is already hot and therefore requires less fuel to convert to steam significantly. Condensate reuse also reduces the volume of cold water, chemicals and water corrections for the boiler. Finally, removing condensate to the water supply system can reduce sewage and wastewater treatment costs.

Consider a boiler return system for the largest users of steam to increase boiler efficiency. This keeps your condensate at a higher pressure and since it does not return, you will return more water to your boiler at a higher temperature.

Install an economizer to increase boiler efficiency.Increase boiler efficiency by reducing excess air

The boiler needs extra air for complete combustion. Although necessary, too much air can result in completely different performance for your boilers. Too little air causes the boiler to produce smoke and dangerous carbon monoxide, while excessive air reduces the efficiency of the boiler. Fortunately, there are automatic combustion control systems that can intelligently monitor the amount of air required for your combustion systems. As described above, adjusting can make your torch work best, even if it is an old torch.
Upgrading to a high-performance burner will save a significant amount of fuel and cost. In many cases, torch upgrades can save on gas bills!

Reduce water overflow

  • Here the overflow means that the boiler water is the steam coming out of the boiler with water.
  • This water carries impurities like dissolved solids

These impurities around the steam system are embedded in complex components such as control valves and pressure regulators, causing high damage and increasing maintenance costs. By reducing these disadvantages, you help increase the efficiency of the boiler.

  • For example, for boiler efficiency, this humidity reduces the content of the steam unit at the end of use.
  • Basically, this is more water that is heated in the boiler but does not give off useful heat before going into the distillation system.
  • An overflow can occur for a variety of reasons, and the solution depends on the cause. Operational problems such as rapid loading, excess soluble solids, or poor separation equipment may be to blame.

So note how the water quality of the boiler feeder can affect the boiler operation.
