Henan newly installed gas 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.

Hot water boiler fuel Henan applicable fast boiler Horizontal hot water boiler fuel suitable for use: pharmaceutical, chemical, light industry, textiles, building materials, aquaculture, food and beverage, foam, printing, washing, rubber, paper, wood processing, hotels , clothing and so on. Product description: WDR automatic level series electric heating steam boiler furnace using separate embodiment of the electrical control cabinet, to avoid thermal aging of the electrical components, affects the life of the boiler.

Having a simple structure, high mechanical strength, easy to replace, and long life. Vapor space, good steam quality. Electromechanical separation installation, the electronic control elements away from heat, allows for heat dissipation. It may be used in parallel with one or more units. PLC programmable control computer and a display screen; automatic control temperature set by the man-machine interface. The display shows the operating parameters, status and fault alarm. Features 1, intelligent automatic control technology, without duty. Flexible working mode can be set to manual or automatic 2. Automatic operation of the boiler period may be set as desired, and set a plurality of different operating time, the boiler can start each time sharing group auto-heating, and switching the heating cycle set, the respective contacts can simultaneously use the same frequency. Improve the life of the equipment. 3, the automatic pressure control, calculus, tracking, starts and stops the water pump and the electric heating tube to automatically load changes, may be manually controlled. 4. With leakage protection, water protection, ground fault protection, steam overpressure protection, overcurrent protection, power protection and other full protection, the boiler automatic protection, safe home. 5. Boiler furnace using steel boiler, furnace longitudinal and circumferential weld X-ray inspection to automatic welding, and. Small furnace and easy to install and mechatronics match. Large boiler furnace designed separately with the electronic control, the influence of a high temperature furnace by electrical control of the electronic control unit is stable. 6, compact structure, scientific and rational design and manufacturing process, so that the boiler space is small, easy to transport, space-saving use. 7. No noise, no pollution, high thermal efficiency. Boiler insulation of high quality insulation material, low heat dissipation, energy saving. Eight. Boiler packaging design using well-known color plate, elegant appearance, easy to rust. 9. All electrical components are CE and CCC certification mark to ensure product safety and service life. 10. Circuit design, wiring is good, clean and reasonable, operation is extremely convenient. 11. Electric heating furnace body flange connection, easy disassembly and maintenance. The present invention has an automatic water supply, water, over-temperature, over-pressure, automatic power failure alarm, leakage protection security systems. 13.PLC computer display and programmable control, to achieve automatic control temperature is set via the HMI, the display device can display the status and operating parameters of the fault alarm.

To meet the domestic water boiler manufacturers also 1, electric boilers: electric boiler today is the most energy saving boiler, the government also tried to promote the product, the product is easy to operate during use, easy to control, it is the first choice for home heating, but boiler gas boiler use is still relatively expensive. 2, gas boilers: gas boilers moment also present a good product, gas boilers and boiler floor is divided into two kinds of boilers to meet ordinary family life mainly boiler heating, convenient and space-saving, wall-hung boilers not only we can provide low temperature hot water floor heating systems, but also to meet domestic water. Home heating or gas-fired boiler or electric boiler selection, but easy to operate control electric boiler, but also get a lot of families. Gas boilers and electric boilers are cleaning boilers, meet the energy requirements of environmental protection. National Day is coming soon, the water boiler manufacturers also can be said now is the best season maintenance of electric boilers. We are in the heating season each year around November, usually through the use of electric boilers for heating season will be a shutdown, a pre-heating of the following year, in order to ensure safe, we need maintenance. Now is the repair, change. 3, gas boilers: gas boilers although it is a mass product, but also much loved family, the Water Cube Hotel 2 tons of gas boilers, gas boilers but more pollutants generated in the course of their work, to pollute our environment, and such gas-fired boiler has not been approved for use in the relevant sectors.
