Combusion air supplying method of Turbo-burner used high efficiency and low NOx boiler, Turbo-burner used high efficiency and low NOx boiler

摘要

PURPOSE: A combustion air supply method and high efficiency low pollution boiler is provided to obtain a compact boiler, while reducing energy consumption and exhaust of nitrogen oxide. CONSTITUTION: A high efficiency low pollution boiler for heating an object(20) by using a burner(10), comprises a turbine(30) installed in the exhaust gas discharge path of the object, and which generates a rotating force by an exhaust air pressure; a combustion air supply compressor(40) installed coaxially with the turbine, and which supplies, to the burner, the combustion air required for interlocked operation with the turbine; an air blower(50) for blowing air to the burner during the initial start of the burner; and an exhaust gas circulating compressor(60) disposed coaxially with the turbine or the combustion air supply compressor, and which recovers the exhaust gas discharged through the turbine and supplies the recovered gas to the burner.
