摘要

以NH

Cl为例

通过一种改进的模拟烟气腐蚀装置

研究了煤掺混生物质燃烧对常见锅炉低温受热面材料的腐蚀特性。结果表明:TA2同时具备极强的耐NH

Cl和H

腐蚀的能力

在实验的温度范围内均未发生腐蚀;316L更容易被高温下的硫酸腐蚀而不易被NH

Cl腐蚀

ND钢与Corten钢耐腐蚀性能较为接近;烟气温度为100~150 ℃时

造成腐蚀的主要原因为硫酸与水蒸气凝结后的硫酸溶液对金属的腐蚀

Cl起到吸收水蒸气与硫酸的效果;烟气温度低于90 ℃时

随着温度的降低

对腐蚀的影响变大。

Abstract

Taking NH

Cl as an example

an improved simulated flue gas corrosion device was used to study the corrosion characteristics of common low-temperature heating surface materials in boiler caused by coal-mixed biomass combustion. Results show that TA2 has strong corrosion resistance to both NH

Cl and H

and no corrosion occurs within the temperature range of the experiment. 316L is more susceptible to corrosion by sulfuric acid at high temperature than NH

while ND steel and Corten steel have similar corrosion resistance. When the flue gas temperature is 100-150 ℃

the main cause of corrosion is the corrosion of metals by the sulfuric acid solution formed by

the condensation of sulfuric acid and water vapor

Cl has the effect of absorbing water vapor and sulfuric acid. When the flue gas temperature is below 90 ℃

the influence of chlorine on corrosion is greater with the decrease of temperature.
