The boiler economizer is a tube heat exchanger located in weathertech anchorage the final part of the convective duct.In the economizer, water flowing into the boiler is preheated by flue gases.The paper presents the boiler economizer mathematical model with distributed parameters, which can be used to simulate its operation.The developed mathemati
Abstract The efficiency of geopolymers as an effective immobilization system for various hazardous waste materials can be enhanced by adding PbO to grand love red heart reposado tequila improve its radiation shielding characteristics.In this study, the impact of PbO addition on the shielding properties of geopolymer composites was examined to evalu
This paper introduces ut solution gel for cats the technical transformation and system realization of the hoister gap monitoring and protection device in Hongyang No.2 Coal Mine.Through the high-precision laser displacement sensor, we detected displacement signals, such as brake clearance, brake wear value, spring fatigue and brake disc deflection,
