china electric heating water tube steam boiler for sale

November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast china electric heating water tube steam boiler for sale - 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.

Open the presentation characteristics of gas-fired china electric heating water tube steam boiler for sale gas boiler includes a gas water boiler, gas hot water boiler, gas steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, as the name suggests refers to the gas boiler fuel for the gas boiler, gas boilers and oil-fired boiler, electric boiler compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. Gas boiler features introduced large font display temperature, easy to grasp and boiler operating conditions of the system, the water temperature can be freely set from 10 ℃ to 90 ℃, automatic boiler or heating system to provide users with life, bath with hot water. The control system controls the temperature of the boiler water circulating pump start and stop, boiler water circulating pump starts when the water reaches an upper limit temperature, lower than the hot water circulation pump stops when the water temperature lower limit. Horizontal bath gas boiler three return all wet back structure, using a large furnace, rough smoke tube design, increased furnace radiation heat absorption, the effective energy saving. Using threaded pipe and waveform furnace, greatly enhanced heat transfer effect, greatly saving fuel consumption. Machine equipped with thermal protection (ultrahigh temperature furnace, the burner is automatically stopped and an alarm buzzer, the second over protection (the boiler shell temperature exceeds 105 deg.] C, the secondary circuit is automatically cut off), anti-dry water protection (when the boiler water level is below low, the boiler is stopped and an alarm beep), a boiler leakage protection (the control system detects electrical leakage, short circuit, automatically cut off the power). press pressure boiler design, the boiler is no pressure state, there is no safety hazard. centrifugal using advanced multilayer insulation wool, a steel sheet for packaging famous white color, heat loss, anti-rust appearance.

First, before regularly shutting down china electric heating water tube steam boiler for sales and inspecting electric furnaces, the following three aspects of preparation should be done: The main contents are as follows: (1) consult the technical file of boiler retrofit electric furnace registration and understand the use of boiler retrofit electric furnace. In order to make the boiler reform electric furnace inside and outside inspection, the general need to know: boiler transformation electric furnace design, manufacturing, installation situation; boiler transformation electric furnace transformation situation; boiler transformation electric furnace operation history and use situation; Boiler retrofit electric furnace water treatment, boiler rules and regulations implementation, and so on.

2) the preparation for stopping the furnace before inspection. First, according to the maintenance schedule, the furnace shutdown date is arranged, and then the boiler revamping electric furnace is shut down according to the normal shut-down procedure, so that the furnace is slowly frustrated. The cooling method can be adopted by injecting gas to dissipate the sinking water, replacing the furnace water for cooling, and cooling by ventilation in the in-line furnace. When the temperature of the furnace water drops to 70 ℃ 80 ℃, the water can be discharged. Open all the doors. When opening the door hole, prevent warm water, steam suddenly spurts out to burn people. The steam, feed water and sewage pipes in the furnace are separated from the corresponding pipes in the boiler revamping furnace in operation. The baffle used for partition should be strong enough to avoid being bulged out by high pressure media. Break position Clear instructions should be given. The flue which is connected with other boiler revamping electric furnaces should also be reliably separated. In addition, it is necessary to remove the soot and scale on the heating surface of the boiler retrofit electric furnace.

3) preparation of inspection tools and lighting. In order to ensure smooth inspection work, inspectors should prepare the necessary instruments, tools, gauges and safe and reliable lighting.

Fuel gas steam china electric heating water tube steam boiler for sale safety and the prevention of fuel gas steam boiler is the flagship product, installation and after many years of production experience, now a comprehensive summary of the accident prevention measures gas boiler fuel and steam to share: fireman who must operate by the quality and technology supervision department issued the use of a registered boiler. Fireman who operate independently of the operating permit required to hold a fireman, and you meet the operational requirements of furnaces and categories. Boiler ignition should be done before the body of the boiler, burners and other auxiliary equipment, all attachments, valves, water supply, gas supply system and the electric control circuit inspection departments, and confirm normal. Play an open air valve, water to the pot water level slightly lower than normal water level. With "manual" to start the fan, the furnace was purged, the control system is adjusted to "auto" position, and then press the "start" switch, the boiler will be according to a predetermined program: Purge - Ignition - combustion - temporarily shutdown. Such as a faulty ignition program, fans can continue to manually purge and re-ignition, such as three unsuccessful ignition, to cease firing and gas, to identify the cause of the fault elimination, in order to re-ignite. When the pot was raised slightly greater than atmospheric pressure, the air valve has steam coming, can close the air valve. Requirements fuel gas steam boiler boost process, according to the provisions of checks and do all the operations carried out in order to confirm or steam supply and the normal furnace. After normal operation, you should always adjust the air supply, air supply and water supply, to maintain the water level and pressure stability, the need to adapt to the load, to ensure that the steam supply. Operation inspection checks should be carried out once every hour, and carry out all the provisions of the recording, check to confirm the name. Class should be flushed sewage water table and each time, the exhaust valve test, pressure gauge should be required to flush the requirements of the trap and check the safety devices perform, record and fill in, sign name recognition. First stop during normal shutdown supply, air supply is stopped later, to keep the water level above the normal water level. Fuel gas steam boiler furnace and flue gas boiler explosions are common in accidents.
