Gas-fired steam generators less than 0.1 MPa go around

 
Steam generator manufacturers here to remind you that the nameplate labeled less than 0.1 of the gas steam generator directly around. This is basically unscrupulous manufacturers, because according to the special equipment directory clearly states that the normal design water volume is greater than or equal to 30 liters of water, and the rated steam pressure is greater than or equal to 0.1MPa so that the steam boiler belongs to the special equipment, the need for supervision, approval, boiler certificate to use. Because the 30L water volume if you want to do 500KG or 1 ton evaporation of steam generator or a great technical difficulty it. This time many manufacturers on the pressure to do something. Less than 0.1MPa most of this production can not meet. They marked less than 0.1Mpa is actually far more than 0.1Mpa but the water volume may be 300L, 500L on the market there are actually 2000L water volume steam generator. This is very dangerous. Special equipment provisions of the 30L and 0.1Mpa exemption is because once higher than this parameter when an accident is likely to cause casualties.
Gas steam generator national test report to detect the water volume is less than 30L, steam pressure 1.0MP ah, does not belong to the special equipment, there is no risk of explosion, no need to report annual inspection;
