plc control gas steam boiler

Such as hotel Home Hotel Group is one of the three major brands, in 300 cities in the country has nearly 2,000 hotels. Home Inns has won China Golden Pillow Award for Best Chinese economy hotel chain brand award, in 2014, Home Inns brand value of $ 420 million of selected China's top 100 brands. April 4, 2016, BTG hotel groups such as the privatization of the hotel purchase transaction has been completed delivery. In mid-2016, as a Beijing hotel with our preliminary communication, the urgent need two boilers work of heating and hot water supply. I related technical engineers and recommend it to calculate the number and size of the boiler on the hotel room as hotel Willy sharp V6-99 two models.

Scale thermal conductivity gas plc control steam boiler is only one out of steel gas steam boiler efficient and environmentally friendly use of non-corrosive cleaning agent in the cleaning process of cleaning the boiler. This will cause the device to the metal tube is exposed to the primary colors, and reduce the effects of biological fouling algae sludge. After ignition gas steam boiler, furnace and to observe the temperature of main steam. Main steam pressure rises, the boiler flue gas temperature significantly higher ignition. If the temperature does not rise, you should immediately to the scene to check the oil gun fire. Scale thermal conductivity gas steam boiler is only one-tenth of steel. When it is scale on the heated surface, which will hinder the heat transfer effect. To maintain the boiler output constant during use, the need to increase the temperature of the combustion side. Gas-fired steam boiler furnace exit temperature rise, increasing the loss of gas steam boiler scale on the device can effectively reduce the water wall heat transfer, the temperature of the water is likely to lead to an increase in the wall, resulting in a wall of water burst. When the gas steam boiler, the furnace will be a series of chemical and physical reactions. During use, it will be effective to form a dense and hard scale on the heating surface, which will lead directly to heat exchange. Due to the scale and efficiency while reducing corrosion can lead to heat gas boiler absorption.

Gaz than plc control steam boiler should be how to calculate? Q: ratio of gas steam boiler gaz simple algorithm is multiplied by the calorific value of coal and boiler efficiency is calculated by dividing this simple assumption does not heat to the steam boiler efficiency of 80%, coal calorific value 5500, if the amount of steam produced a ton of coal can be calculated as follows * 0.8 = 5500/600 = 7.3, ie: gaz ratio of 7.3 can be calculated simply, is this right? A: According to your argument: the amount of steam a ton of coal produced, commonly referred to as the evaporation rate of the fuel, commonly known as steam coal ratio. The calculation formula is: base received low calorific value of coal is then divided by multiplying the thermal efficiency of the boiler (steam heat feedwater minus heat). You said above is correct.

The price of gas boiler characteristics and maintenance of gas boilers Products: gas boiler includes a gas water boiler, gas hot water boiler, gas plc control steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, as the name suggests refers to gas boiler it is the fuel for the gas boilers, 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: 1, 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. 2, the control system controls the circulation pump start and stop in accordance with the temperature of boiler water, 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. 3, three horizontal gas bath boiler 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. 4, while the machine is 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), the lack of anti-dry protection of water (when water is lower than the low water level of the furnace, 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) .5, according to the boiler pressure design , no pressure in the boiler state, there is no safety hazard with advanced multi-layer insulation centrifugal glass wool, steel for packaging famous white color, heat loss, beauty care and anti-rust gas boiler: 1, gas-fired boiler during operation Note the following points: (1) does not allow pressurized gas boiler furnace combustion or smoke, because the manhole cover easy to burn stoker; not on the water bottom (2) gas boiler ground surface to prevent corrosion .2 moisture, gas boiler runs every 2-3 weeks, should be checked once a .3, gas boiler run after every 3-6 months, should conduct a comprehensive inspection shutdown maintenance: (1) internal and external gas boiler inspection, such as by Weld parts, steel inside and outside for corrosion phenomenon, if found serious deficiencies should be repaired, if the repairs were not serious defects also until the next shutdown, if there is suspicious, but does not affect safety, should make a record for future reference; (2) can be checked and the water boiler primer coating to prevent corrosion .4, gas boilers and boiler paint base at least once a year .5, often of unused gas boiler maintenance methods: dry and wet two kinds, one month shutdown, care should be taken dry method, wet shutdown can be less than one month regimen (1) dry regimen: after shutdown of the furnace to the discharge water will completely remove the dirt inside , rinse, drying in the furnace with Weihuo (be careful not to fire), and then the bulk quicklime 10-30 millimeters in diameter installed sub-plate, placed in the drum, without contacting the metal with lime, quicklime by weight, calculated to the drum volume 8 kg per cubic meter, then all manholes, hand holes pipe valve closed, checked every three months, such as lime ingredients like broken, i.e. the need to replace the boiler should be re-run Quicklime and disk unloading (2) Wet regimen: After Shutdown of the water discharge furnace, the inside completely remove the dirt, rinse, refill treated water to the full, the water was heated to 100 deg.] C oven, so that the water exhaust gas out of the furnace, and then close all valves, cold climates where moisture can not support the use of law, so as not to damage the boiler furnace water freezes.
