steam washing machine laundry equipment steam boilers
The pH control of hot water boiler hot water boiler water pH control at 10 and 12, metal corrosion phenomenon does not occur over this range or below this range can cause corrosion, it is necessary to strictly control the pH of the boiler water within a predetermined range, the metal walls of the boiler so that a protective film is formed to avoid corrosion. When the pH of the boiler water is increased or decreased, some measures must be taken, be adjusted to within the specifications. If the pH of the boiler water is lower than 10, can be put in the boiler water an alkaline agent, the pH increased to normal, thus reducing the corrosion of the acidic substance in the boiler water boiler equipment.
By definition, the condensing boiler flue gas is condensed into water vapor, recover its latent heat of vaporization for the boiler, the thermal efficiency of the boiler, or more than 100%. Adding provided condensing heat exchanger can upgrade to a conventional boiler, so that it becomes condensing boilers. We can say that the transformation of traditional boilers condensing boilers can achieve a substantial increase boiler thermal efficiency, the best way to achieve efficient utilization of resources.
November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast boiler - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.
Gas boiler hydrostatic test procedures: gas steam washing machine laundry equipment steam boilers with a certain high pressure, high temperature steam output can be higher than 100 deg.] C, and is clear of the pressure vessel defined. After completion of the boiler installation, as required, hydrostatic testing must be done to verify the tightness between the valve body and the boiler.
