Problems solved by technology

But there are following deficiencies in this technology: (1) small oil gun ignition cannot be used when the boiler cold furnace starts
(2) The ignition of the small oil gun still cannot solve the problem of using the electrostatic precipitator when the boiler is started
(3) When the boiler operates under ultra-low load conditions, the stable combustion capability of the small oil gun is insufficient

Embodiment Construction

[0018] Such as figure 1 As shown, the low NOx oil gun device utilizing regenerative heating includes a micro-oil oil gun 1, a high-energy ignition gun 2, a Venturi air duct 3, a Venturi air inlet pipe 4, a total air inlet pipe 5, a cyclone 6, a return Hot channel 7, ceramic combustion chamber 8 and shell 9, ceramic combustion chamber 8, swirler 6 are arranged inside the shell 9, swirler 6 is connected with venturi air duct 3, and venturi air duct 3 is provided with venturi The air inlet pipe 4 is connected with the main air inlet pipe 5 on the shell 9, and the inlet end of the Venturi air duct 3 is provided with a micro-oil gun 1 and a high-energy ignition gun 2.

[0019] The return flow of hot flue gas produced by fuel combustion in the oil combustion chamber at the rear end of the swirler 6 is 2%-10% of the total flue gas volume. After the reflux hot flue gas and oil mist are mixed, the mixing temperature reaches 200°C-350°C. The ratio of the throat area of ​​the Venturi a...

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 invention relates to a burner, in particular to a low NOx oil gun device utilizing regenerative heating. Background technique [0002] In 2004, my country imported about 120 million tons of crude oil, which is expected to exceed 140 million tons in 2005, and the dependence on imported crude oil has reached 40%. Petroleum has now become a strategic material related to my country's economic security. [0003] Premier Wen Jiabao of the State Council made a government report at the Tenth National People's Congress on March 5, 2005, emphasizing the need to pay attention to the conservation and rational use of energy resources. Premier Wen said, "To alleviate the contradiction between my country's energy resources and social and economic development, we must base ourselves on the domestic market and significantly improve the efficiency of energy resource utilization." [0004] Large-scale power plant boilers consume a huge amount of oil for ignition an...
