An air duct provided at the contact economizer preheater, the apparatus may effectively increase the temperature of the combustion air and the fuel to improve ignition conditions. Very beneficial to the boiler combustion conditions.
3, the combustion system modulating bidirectionality factory fuel boiler design specification has a certain flexibility, different media in effect outside the combustion process are different, adjusting the embodiment, with the economizer and the air preheater using, the boiler temperature exhaust emission control at a suitable temperature, that make full use of heat energy, but also to ensure the integrity of the structure and function of the relative equipment, environmental protection, energy saving, security and development for all of us social responsibility.
