Abstract

Prolongation of heat and power equipment resource, which for the time being, is the only way out of the critical situation, gives a significant economic effect. Considering the uniform nature and low rate of low-temperature corrosion when burning water-fuel emulsions with water content of 30%, method for estimating service life of metal low-temperature heating surfaces at pipe metal surfaces temperature above 60°C has been proposed, at which uniform corrosion is observed. In the published literature, there are practically no data of impact on service life of low-temperature heating surfaces simultaneous influence of corrosion rates on gas and water sides of heating surfaces. The reliability of conclusion about the reliability of pipe heating surfaces largely depends on validity of conclusions made on the basis of calculations and especially taking into account experimental data of processes affecting reliability. It is on the basis of calculation results that it is possible to identify most tense elements that need to be subjected to detailed control. Therefore, in essence, reliability of entire methodology for assessing achieved and remaining resources depends on them. The paper presents a method for conducting computational studies of simultaneous influence of corrosion processes on gas and water sides of pipes and comparative assessment of service life of low-temperature heating surfaces when the limit states of metal are reached at acceptable and limit values of tensions and minimum possible thickness of pipe wall under influence of gas-chemical and water-chemical regimes and considering the data of experimental studies of processes affecting the reliability of work. To determine the time of calculated and residual service life of metal under uniform corrosion, a method for determining minimum residual thickness of metal has been presented, which still provides predestructive maximum allowable tension for remaining pipe wall thickness
