Are there any explosion protection requirements for the waste heat boilers in gas turbine combined cycle systems and those used in waste incineration?
Thread Content
According to safety regulation 3.22, for water-tube boilers with a evaporation rate of ≤75 t/h, explosion vents must be installed in the absence of an automatic furnace protection system. I have a few questions: 1. For boilers with an evaporation rate greater than 75 t/h, is it possible to omit explosion-proof doors or an automatic furnace protection system? 2. Are there any explosion-proof requirements for the flue in the waste heat boiler of gas turbine combined cycles? As far as I know, these flue-type waste heat boilers don’t seem to be equipped with such features at present; are there any relevant standard specifications? 3. Regarding the waste grate incineration system’s waste heat boiler section, are there any requirements regarding explosion-proof devices? How should this be understood?
It is not determined by the name of the boiler whether explosion protection is needed; rather, it depends on the boiler’s fuel, the environment in which it is installed, and its combustion characteristics. Typically, waste heat boilers are used for recovering large amounts of heat in petrochemical processes. Since it is specified as a gas turbine combined cycle, the fuel for such gas turbine units is generally a combustible gas, right? Explosion protection definitely needs to be considered. Regarding waste incineration, it depends on the nature of the waste and the fuel used in the incinerator; some wastes may pose a risk of combustion or explosion due to the presence of volatile organic compounds, and if gas is used as a fuel for supporting combustion in the boiler, then it as well must be explosion-proof.
