Embodiment Construction

[0015] attached Figure 1-2 It is a specific embodiment of the present invention. The invention is a copper-chromium-based TGr-titanium film threaded tubular air preheater and tube film components, including a base pipe 1 and a copper-chromium-based TGr-titanium film layer 2, and the outer side of the base pipe 1 is provided with a copper-chromium-based TGr - Titanium film layer 2 .

[0016] Further, the weight percent of the main components of the copper-chromium-based TGr-titanium film layer 2 is: TGr-50 10%, MnO2 5%, CuO 9%, NiO 3%, LiCO3 2%, B2O3 6%, TiO2 9% , Pb2O3 2%, MnO2 5%, K2O 5%, SiO2 44%.

[0017] Further, the processing technology of a copper-chromium-based TGr-titanium film threaded tubular air preheater and tube-film components includes the following steps: preparing charged copper-chromium-based TGr-titanium powder—pretreatment—embossing ——Automatic spraying——Sintering—Cooling off-line——Assembly.

[0018] Further, the base pipe 1 is a threaded pipe, and the...

Abstract

The invention belongs to the technical field of new energy, efficient energy saving and energy saving of high-energy-consuming industries such as a power industry and particularly relates to a copper-chromium-based TGr-titanium film thread pipe type air preheater and a pipe film component. According to the copper-chromium-based TGr-titanium film thread pipe type air preheater and the pipe film component, a base pipe and a copper-chromium-based TGr-titanium film layer are included. The copper-chromium-based TGr-titanium film layer is arranged on the outer side of the base pipe. The copper-chromium-based TGr-titanium film thread pipe type air preheater and the pipe film component have the advantages that the heating area can be increased through threads, so that air side heat transferring capacity is greatly improved, meanwhile, flue gas flow speed is reasonably selected, under ripple disturbance, ash deposition phenomena hardly exist, heat transferring capacity is improved, so that wall temperature is improved, low-temperature corrosion is lowered, flue gas side heat is well used, the burning state is improved, and efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy, high-efficiency energy-saving, electric power and other high-energy-consuming industries, and specifically relates to a copper-chromium-based TGr-titanium film threaded tubular air preheater and tube film components. Background technique [0002] At present, whether it is an industrial boiler or a power plant boiler, low-temperature corrosion and ash plugging of the air preheater are common, which directly affects the safe operation, economical operation and emission of the boiler and the unit, especially when burning high-sulfur coal. The problem is even more serious. The air preheater in my country's thermal power plants accounts for 6%-8% of the overall boiler investment, and the direct cost of equipment replacement and shutdown cleaning caused by low-temperature corrosion and ash blocking each year accounts for about 4%-5% of operating costs. In addition, the loss caused by the shutdown o...
