How to Improve Gas Boiler Efficiency

How to improve gas boiler efficiency ? Many clients often asked this questions.

1. Air Preheaters
Air preheaters recover waste heat from flue gas and then use it to preheat combustion air. There are two main types of preheaters: recuperators and regenerators. A recuperator system is installed in a gas boiler stack and transfers heat from outgoing gas to incoming air. A regenerator, on the other hand, includes heat storage sections that transfer heat from flue gas to combustion air.

2.Replacement gas fired boiler burners
At a certain point, it makes sense to replace or retrofit them. Whatever type of gas boiler you have or fuel you burn, there are many burner options to consider when contemplating a replacement. If you aren’t in a position to opt for new gas boiler burners, retrofits can provide significant savings at a fraction of the cost.

3. Economizers
Much like preheaters, gas fired boiler economizers take waste heat and transfer it to a gas boiler’s feedwater, rather than combustion air. Preheated water is obviously closer to the temperature needed to produce steam, so this saves energy when the preheated feedwater enters the steam drum or furnace. Economizers also offer the added benefit of reducing the chance of thermal shock by minimizing water temperature fluctuations.

4. Gas fired boiler Insulation
It seems obvious, but industrial gas fired boilers need to be insulated to minimize heat loss. Because industrial gas boilers are so big, they have massive surface areas that are vulnerable to significant heat loss if not insulated properly. The primary type of insulation used for industrial gas boilers is the refractory material that lines them. When replacing refractory materials, make sure to do a structural analysis to determine how much weight your boiler can support.

5.Regular Maintenance
It is important to have a regular boiler maintenance for boiler efficiency. While all of the suggestions above can make a significant difference if implemented correctly, they also involve installing or replacing equipment. And with more equipment comes more chances for malfunctions. A good maintenance program will slow equipment deterioration, enhance efficiency, maintain reliability, and ultimately reduce operating costs.
