Why Our High Efficiency Condensing Boiler is inefficient?

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Example A boiler operates for 8,000 hours per year and consumes 500,000 MMBtu of natural gas

The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature. • Insulate the jacket of the boiler to reduce heat losses. The improvement of the boiler efficiency depends on the surface

how to improve boiler efficiency

Aug 11, 2020 · So the temperature of the flue gas exits at a lot lower temperature of about 40°C. You're keeping the heat in the boiler longer, keeping in and condensing it down as it cools down, you get condensate dripping off the heat exchanger. Keeping the heat in the appliance longer and making use of this heat to increase the condensing boiler efficiency.

Jan 08, 2016 · Existing heating systems can have pumps retrofitted with variable frequency drives (VFDs) that can further improve the efficiency of the system. Wider delta T can also help lower the return water temperature resulting in higher condensing rate contributing to higher boiler efficiency.

attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Suggested Actions Boilers often operate at excess air levels higher than the optimum. Periodically monitor flue gas composition and tune your boilers
