excessive effects
1.The recommendations assume that, in the aftermath of major hurricanes or floods, buildings wet for >48 hours will generally support visible and extensive mold growth and should be remediated, and excessive exposure to mold-contaminated materials can cause adverse health effects in susceptible persons regardless of the type of mold or the extent of contamination.
4.Results show that all the geometric parameters have remarkable effects on combustion performance; the swirl of intake air generated by skew intake holes enhances fuel-air mixing, minimizes dead zone and stabilizes the flame with reverse flow, but the excessive reverse flow can cause overheat in combustion chamber and exhaust; the consistency of flow resistance in intake and exhaust system is conducive to the stability of heater performance.
