Henan newly installed gas combined 2 ton electric hot water boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.

The system mainly composed of Shandong Shandong gas combined 2 ton electric hot water boiler gas boiler has now become the main lot cell equipment, schools, hot water heating, has the advantage of short heating to a temperature depending on the use and characteristics of highly stable gas boiler Shandong such devices, and Shandong gas boiler manufacturers for the sale of the control is relatively strict, let's look at the main gas boiler system Shandong composition: 1 air supply system Shandong gas-fired boiler air supply system is a more important part, because the gas in the combustion the process requires a certain amount of oxygen can guarantee full combustion of gas, so the air supply system has its own throttle controller, fan motor and fan and other parts, also in strategic locations and connected to the monitoring system to ensure timely delivery of understanding air system operating conditions; 2. ignition system according to another group of Shandong gas boiler system for the ignition system, ignition system object exists mainly in order to ignite the fuel, the ignition system comprising ignition transformers, ignition electrodes and the like, and to the electrical steps must arrange fire personnel hand Moving operation, Shandong gas boiler in order to protect security so using a manual procedure to complete the ignition operation; 3 monitoring system Shandong gas boiler also uses a monitoring system, in order to ensure that the process gas boiler operation, the air pressure, temperature real-time monitoring, when something goes wrong the first time it is possible to cut off the power supply startup protection and warning procedures to improve the safety performance of Shandong gas boiler operation, the monitoring system is a safety factor of gas-fired boiler system infrastructure upgrade; Shandong gas boiler is not only the air supply system , ignition system and monitoring system also includes a fuel system and electric control system, so this system is the basis of the five gas-fired boiler system is also essential systems. In the process of using the gas boiler in Shandong we should also pay attention to its maintenance, Shandong, use and maintenance of the gas boiler is also relatively easy way, can effectively reduce the workload and long working staff.
