Common Problem and Solution gas electric instant hot water boiler 1, the power supply is turned on, by cause of failure is not running after starting the motor are: (1) locking pressure less; (2) solenoid valves lax, joints leak, check the lock; (3) thermal relay opens; (4) condition loop at least one is not satisfied (water level, pressure, temperature, and the programmable controller is powered starter) Remedy: (1) adjusting the air pressure to a predetermined value; (2) cleaning or repair of the solenoid valve conduit linker; (3) press the reset element checks whether the motor current and damage; (4) check the water level, pressure, temperature gauge 2 if, after the normal purging before the start, but misfire malfunction Cause: (1) the amount of electric anger ; (2) the solenoid valve does not work (the main valve, an ignition valve); (3) a solenoid valve burned; (4) pressure instability; (5) the air volume is too large Remedy: (1) inspection and repair line; (2 ) renewal; (3) to adjust the pressure to a predetermined value; (4) decreases with the wind, to reduce the throttle opening 3, misfire, normal air pressure, there is no ignition power failure causes: (1) the ignition transformer burnout ; (2) high-voltage damage or loss; (3) the gap is too large or too small, the relative size of the firing rod position; (4) and electrode breakage or Short circuit; (5) inappropriate pitch, Remedy: (1) renewal; (2) or re-install new ones; (3) 4 readjust after the 5S flame lit, fault cause: (1) is less than atmospheric pressure, too much pressure drop, gas flow is small; (2) air flow rate is too small, incomplete combustion, darker smoke color; (3) the air volume is too large, the gas appears white Remedy: (1) re-adjusting the air, the filter cleaning ; (2) 5 readjusted, fault cause white smoke: (1) air flow rate is too small; (2) too much humidity; (3) a lower exhaust gas temperature, Remedy: (1) transfer of small damper; (2 ) appropriate to reduce the air volume and improve the inlet air temperature; (3) take measures to increase the exhaust gas temperature 6, chimney dripping failure reasons: (1) ambient temperature is low; more (2) a small fire combustion process; (3) gas hydrogen-peroxide amount generated water; (4) long chimney Remedy: (1) reducing the amount of air distribution; (2) reducing the height of the chimney; (3) increase the oven temperature; (4) than the exhaust gas temperature low, stopping state under the control of the damper, the damper position switch signal is not fed back to the program signal, throttle check whether the wiring is loose or switch failure.
Chinese wine culture has a long history, wine blend. In the process of making wine, almost all wine prices are inseparable from the brewing process steam, we can say the stability and quality of steam purity of the wine production plays a decisive role. Lefort Wine has been committed to producing high-quality wine products, December 2016 No. 1, Lefort wine and I signed a one 4 tons of steam condensing steam electric instant hot water boilers, the company continues to provide high-quality wine work steam.
Laundry hotel special reference to the current selection of steam electric instant hot water boilers Hotels generally use the hot water boiler for heating and sanitary hot water, kitchen utensils gas can be directly used, but still need to supply steam laundry room, laundry room steam supply pressure to be 0.4-0.6 MPa, generally an amount of steam in the hotel laundry 0.5 ~ 2.0T / H, steam day with about 3 to 10 tons. Under the premise of the city's coal-fired boilers can not be used, the choice of energy sources natural gas, diesel, liquefied petroleum gas, electricity, in what exactly it is more appropriate? First use to compare the cost of various energy sources, according to Henan hotel energy prices, natural gas is 3.0 yuan / Nm3, diesel 9.0 yuan / kg, liquefied petroleum gas 15 yuan / Nm3, the price of 1 yuan / kwh. Compare 1 ton of steam produced by a variety of energy costs as follows: Energy Category Energy calorific value of natural gas in energy costs per ton of steam 8600kcal / Nm380m33.0 yuan / Nm3240 yuan / ton diesel 10400kcal / kg66kg9 energy consumption per ton of steam energy prices. 0 yuan / kg594 yuan / ton liquefied 22000kcal / Nm331m315 yuan / Nm3465 yuan / ton electric 1kwh700kwh1 yuan / kwh700 yuan / ton Note: energy consumption efficiency estimated by conventional steam boiler; Nm3 refers to the standard state volume of gas M3; calculated from the above analysis, the use of natural gas per ton of steam lowest cost, most economical operation, electrically heated steam up costs. Gas steam boiler typically 2 to 3 sets of selection, single nominal amount of evaporation 0.5T / H ~ 1.5T / H. Gas-fired steam boiler boiler range belong to the state regulators, the need to build a separate boiler room, not like pressure hot water boiler as the main building or in the basement, while the city hotels are often difficult to have a location to build a separate boiler room. In recent years, there is a new type of gas steam boiler, the water capacity is small (less than 30L), a single evaporation accessible 1T / H, do not belong to the state boiler steam boiler regulation range, can be in the basement, a good solution to the conventional steam boiler no suitable location problems.
How to observe whether steam electric instant hot water boiler is short of water and how to deal with itSteam boiler is a kind of energy conversion equipment. The energy input to the boiler is chemical energy in fuel, electric energy, heat energy of high temperature flue gas and so on. After boiler conversion, steam, high temperature water or organic heat carrier with certain heat energy is outputted out. Water level below the minimum safe water level, or invisible water level, water table glass tube (plate) appears white. The two-color water level meter shows all the gas-phase indication colors. Low water level alarm signals occur in high and low water level alarms. Low water level interlock device, water level below the specified value should stop the operation of fan, induced fan, grate reducer motor. There is also a sharp rise in superheater steam temperature above the normal outlet Steam temperature. The exhaust temperature of the boiler rises. The feed water flow rate is smaller than the steam flow rate, if the furnace tube or coal economizer tube rupture cause water shortage, the opposite phenomenon will occur. When the water shortage is serious, you can smell the scorching smell. When water shortage is serious, red water wall tube can be seen from the furnace door. When the water shortage is severe, the furnace tube may break, and a burst can be heard, steam and smoke will be ejected from the furnace door and the fire door. By calling water; for severe water shortage, it is necessary to stop the furnace urgently, and blindly feed water to the boiler. Reduce fuel, blast, draw wind, and supply water slowly when water is classified as a slight water shortage.
