Electric central heating hot water boiler from china suppliers

According to fuel (electricity, oil, gas), oil-fired gas electric central heating hot water boiler from china suppliers can be divided into three kinds: electric steam boiler, oil-fired steam boiler and gas-fired steam boiler. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small and medium-sized steam boilers are mostly single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. The following is the boiler pressure fire shutdown time more than 6 hours, the boiler main steam valve should be closed after a period of pressing fire, opening the superheater outlet header drain valve, to cool the superheater. If the air pressure rises after the main steam valve is closed, it can be used to lower the pressure of the boiler by feeding the water into the boiler and simultaneously discharging the water. Press. When the boiler resumes operation, it needs to go through the pressure rise and protect step 2. There is still steam pressure in the pot during the shutdown period of the pressure fire, so it is still necessary to pay attention to monitoring and make the boiler keep the allowable water level 3, the boiler with cast iron gas saving gas, after the boiler stops feed water, The gas-saving flue baffle shall be closed, the side-hearth baffle opened or used in the circulating pipeline to stop the water temperature in the gas-saving area exceeding the specified value of 4, the proper discharge shall be carried out during the shut-down of the furnace under pressure fire, and the sediment in the furnace shall be excluded. The operation of circulating water pump should not be stopped immediately after the furnace shut down. The circulating water of network should be kept circulating in the system for a period of time, and the water temperature of boiler outlet should be lowered below 50oC. The operation of circulating water pump can not be stopped until the operation of circulating pump is stopped.

The purchase of gas-fired electric central heating hot water boiler from china suppliers, we are more anxious shopping center, but for gas-fired boilers are not very understanding. After the introduction of others, we understand each other fast boiler more comprehensive, and more trust fast boiler. After the boiler put into use, it turns out, party fast products fully meet the needs of our shopping centers. --customer feedback

The system mainly composed of Shandong Shandong gas electric central heating hot water boiler from china suppliers 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.
