briefly explain by boiler

Fangkuai Boiler is a clean-up briefly explain by boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.

How should we do when run dry gas briefly explain by boiler? When the water level below the safety gas boiler water line, and the water table or invisible water glass is in the form of white. On the gas boiler generally have the lowest water level alarm, that is, when the low water level alarm signal occurs, it will sound an alarm number. When the low water level is required to be a predetermined value in accordance with the blower, Fan, grate reducer motor stops running. Superheater steam temperature gas boiler water is rising, which is usually a temperature higher than the vapor is normal. When gas boiler water shortage, the water flow is less than the flow of steam. When the water because if the furnace tube or pipe rupture caused by the economizer, steam flow which is great. Then add water to the boiler is required not need much.

Electric steam briefly explain by boiler of the heating process since the water temperature in the steam boiler power rising bubbles and an evaporator heating surface of the metal wall temperature began to rise at any time, need to pay attention to thermal expansion and thermal stress temperature, the wall thickness of the bubbles due to the relatively thick, the main problem in the electric steam boiler is heated during thermal stress. At the same time, but also consider the overall thermal expansion problems, especially for the electric heating surface of the steam boiler tubes, because the wall thickness, length of problems in the heating process is thermally integrated for expansion, but also noted that the thermal stress and prevent because of the neglect caused the failure. Generating steam in electric steam boiler and boost heating process, the temperature difference between the bubble there is a temperature difference along the thickness of the vertical wall and, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall surface temperature is above the lower case, to prevent excessive thermal stress, the boiler must be slow step. Electric steam boiler ignition during the boost process, the steam parameters of the boiler, the water level and the working conditions of the various components is constantly changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, be sure to arrange professional staff to closely monitor a variety of changes in the meter indication. By adjusting the control pressure, some of the process parameters of temperature, the normal water level in the range of the allowable, but also the reliability of the assessment, a variety of security instruments, valves and other components, so as to ensure adequate safety and stability of electric steam boiler run. The higher pressure steam boiler electrical energy consumption will be higher and higher, the corresponding steam pressure equipment and piping, and the valve will also increase accepted, which also makes the protection needs of conservation relative increase steam boiler, and steam generated in the heat generation and transport processes and also increase the proportion wandered.

When the enterprise receives the steam briefly explain by boiler, for the normal use of the boiler and the self-safety of the enterprise operators, it must strictly abide by the "Safety production Law". Interim regulations on Safety Supervision of Boiler and pressure vessels relevant provisions of Safety Technical Supervision regulations for Steam boilers. These regulations shall apply to pressurized fixed steam boilers in water media, including coal-fired steam boilers, oil-fired steam boilers and gas-fired steam boilers. The factory that uses boiler should have corresponding technical certificate, technical document of installation boiler and construction quality attestation at the same time.
