How To Solve Coking Waste Heat Boiler Corrosion

2016-05-13

Large quantities of heat energy inherent in exhaust gases from various industrial processes can be recovered in waste heat boiler to reduce energy consumption. In coking industry, we offer coking waste heat recovery boiler that can reuse waste heat and reduce energy consumption, while during its operation, low temperature corrosion might occur and affect the boiler’s service life. Once the corrosion occurs in coking waste heat boiler, we must timely take measure and solve it.

Measures to solve coking waste heat boiler corrosion

1.During the operation, paying attention to adjust its combustion, control the excess air ratio in a reasonable range, prevent primary wind from rushing the wall, avoid reduction gas occur nearby burner wall, meanwhile improve the corrosion resistant ability of waste heat boiler metal.
2.Strictly control the coking waste heat boiler water PH value, regularly (every two hours) inspect boiler water PH value. When the PH value is less than 10, operator can increase the dose of tricalcium phosphate, and sodium hydroxide to adjust the value.
3. To prepare for the maintenance of the boiler. After coking waste heat boiler shutdown, it would be better to adopt dry maintenance, discharge all the water clearly, with a small fire drying out moisture, then add 2 ~ 3 kg lime-stones or calcium chloride per cubic meter inside boiler volume, to ensure boiler wall’s drying, so that we can effectively prevent corrosion during deactivation.

Manufacturer and supplier of waste heat boiler

ZG Boiler offers years of experience utilizing waste gases and recovering its energy, the coking waste heat recovery boiler is an ideal equipment to recover waste heat energy from coking process. Besides, we’re also provide overall after-sale service, technical support to help solve any problems during our boiler operation.
