Continuous automatic adjustment of water supply, drum, induced draft fan damper flap opening remote control, remote pump control valve (an intake gas boiler control valve), a heavy oil combustion boiler should automatically adjust the oil, gas boiler should automatically adjust the air pressure, there is superheater boiler there should automatically adjust the temperature of superheated steam. 3) alarm and protection. High and low water level indication and alarm, low water level limit protection, over voltage protection and alarm indication of heart steam, oil accident alarm system, furnace flame protection, fuel gas overpressure protection or low temperature alarm and protection. Boiler superheater should have more limited temperature of superheated steam and an alarm indication. 4) control and the other. Drums, Fan, and start and stop the pump interlock control program, drum, fan baffle opening damper indicated, shall be provided with explosion-gas boiler electrical control equipment.
Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam boiler steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Oil fire tube fired hot water boiler structure design is how to avoid the danger of explosion of fuel hot water boiler hot water boiler dedicated micro-controller configuration, large-screen full Chinese LCD screen with super bright backlight, day or night, the boiler operation status is clearly visible. Display complete: circulating pump, the operation of the burner, the boiler water temperature, water level, the current time, alarm records, ranging boiler operating state; easy setup: the boiler power, the operator can freely enter key 6 when operating parameters for the standby state (set) into the operating state (power on), the state out of operation (stop), the random standby state is set; functional: arbitrarily set the current time, alarm temperature, the maximum temperature of water, The lower limit of water temperature, the temperature of the circulation pump is turned on, the circulation pump shutdown temperature, the boiler switch time (divided into four time periods) and other operating parameters. The operator usually just press the start key to boot, press the stop button to stop, very simple. Oil hot water boiler structure design is how to avoid the danger of explosion by the fuel pressure hot water boiler structural design, top with a through large pores, boiler work under pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, fully optimize the size of the boiler, the form of coordinated appearance. Vertical CLHS mounted boiler combustion at the burner, the fuel is combusted within a slight positive pressure furnace, the flue gas temperature in the furnace radiation heat transfer, convective heat transfer and then enter the pyrotechnics, smoke box is discharged through the last. Smoke tube baffle is inserted, the smoke evacuation slow speed, heat strengthening, fuel combustion furnace to ensure the greatest degree of heat generated water, greatly improve the thermal efficiency of the boiler; CWNS horizontal boiler with full wet back three return structure, the flue gas flow length, reduced exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively prevent the metal due to thermal expansion and contraction result in reduced equipment life; large-diameter cigarette tube and macropores bridge the gap, the boiler at equal time scale coating thin and easy to clean.
If within the natural gas boiler wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the steam boiler. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.
