Industrial boilers are widely used and can be used in industrial production in many industries, such as sterilization, disinfection, bleaching, washing, pulping, maintenance, etc. Different process requirements are different, so the selected boiler parameters are different. However, no matter what industry it is, the user's needs are the same, that is, the selected boiler must be energy-efficient enough. What is the role of boiler economizers, and how often do boiler inspections need to be done?
1. Function of boiler economizers
The efficiency of industrial boilers is about 70%, and flue gas heat accounts for the vast majority of the wasted heat. Normally, the exhaust temperature of steam and hot water boilers is above 200℃, and the exhaust temperature of heat carrier boilers is above 280℃-350℃. This part of heat can be recovered by using boiler economizers or waste heat boilers, which can be used to increase the boiler inlet water temperature and blast temperature, thereby improving the boiler thermal efficiency and reducing the boiler operating cost.
2. How often should boilers be inspected
1. Boilers are inspected regularly once a year, and boilers that have not been inspected regularly for safety shall not be used. Boiler safety accessories: Safety valves are inspected regularly every year, and pressure gauges are calibrated every six months. Safety accessories that have not been inspected regularly shall not be used.
2. Boiler inspections require plans and programs, and safety inspections should be carried out according to different use periods. The regular inspections of boilers mainly include external inspections, internal inspections, and water pressure commissioning.
3. Starting from these three directions, problems can be discovered in time, so that problems can be eliminated and safe and stable operation can be ensured. When conducting external inspections of boilers, there is no need to shut down for inspection. Inspections can be carried out when the boiler is in normal operation, and reasonable inspections and assessments of the safety status of the boiler can be made.
4. There can be a certain time interval for external inspections, generally once a year, to detect problems in time; when conducting internal inspections of boilers, in order to ensure safety, it is necessary to conduct them when the boiler is shut down. By inspecting the internal equipment and components of the boiler, the safety can be reasonably assessed. This type of inspection frequency can be carried out every two years.
5. The inspection of water pressure commissioning is mainly carried out on boilers with water as the medium, and the pressure specified in the boiler standard is calculated.
