Energy conscious home and business owners, school and hospital administrators are always looking for opportunities to reduce operating costs. Replacement of old heating systems with more reliable, energy efficient heating systems is one way to offset rising energy costs. Boiler OEMs have responded to market demands by developing condensing boilers that provide consumers with high energy savings and comfortable hydronic heating.
As a pioneer in the boiler industry for more than 25 years, ebm-papst knows the importance of delivering a measured air-fuel mixture consistently to the burner. If the ratio of gas to air is too high, the gas is not completely burned off, resulting in wasted energy and incomplete combustion. If the gas content is too low, the burner may not light and the system will shut down.
The best solution? A pneumatic or electronically controlled gas-air ratio control system that continually adapts to heat demand with a 5:1 modulation range or an electronic system that continually adapts to changes in gas type, gas quality, altitude or vent length with an increased 10:1 modulation range.
The company’s new condensing boiler technology catalog presents combustion engineers who are developing high efficiency condensing boilers with a variety of options from components to complete system solutions for their efficient premix combustion applications. Whether it's a premix gas blower or a complete pneumatic or electronic gas-air ratio control system, ebm-papst provides engineered solutions that match the performance requirements of the condensing boiler design.
The ebm-papst system includes many features. The first is a low-noise, long life premix gas blower for modulating the air-fuel delivered to the burner. Next is a venturi that creates a pneumatic coupling between the blower and the gas valve. Additionally there is a zero-governor gas valve that optimizes the gas-air mixture. Finally, an electronic burner control with a prominent LCD display insures the proper sequential operation of the complete combustion cycle.
