Abstract

A low NOx oil gun utilizing returned heat to heat is prepared as setting ceramic combustion chamber and swirler in shell, connecting swirler with Venturi wind channel being set with Venturi wind inlet, setting general wind inlet tube on shell and setting oil gun of micro oil and ignition gun of high energy on inlet end of Venturi wind channel.

Description

technical field [0001] The present invention relates to a burner, in particular to a low-NOx oil gun device heated by recuperation. Background technique [0002] In 2004, my country imported about 120 million tons of crude oil, and it is expected to exceed 140 million tons in 2005. The dependence on imported crude oil has reached 40%. Oil has now become a strategic material related to my country's economic security. [0003] Premier Wen Jiabao of the State Council emphasized in his government report at the 10th National People's Congress on March 5, 2005 that attention should be paid to the conservation and rational use of energy resources. Premier Wen said, "To ease the contradiction between my country's energy resources and social and economic development, we must base ourselves on the country and significantly improve the efficiency of energy and resource utilization." [0004] Large-scale power station boilers consume a huge amount of oil for ignition and low-load stab...
