Sandwich pot with steam generator, steam generator much money, Urumqi steam generator ..

Gas boiler in normal operation, sometimes occur suddenly went phenomenon. 1. boiler flameout phenomenon (1) furnace pressure increases suddenly. (2) the furnace is dimmed by watching the fire holes do not see the flame. (3) steam pressure, steam temperature drops. 2. The gas boiler flame reasons (1) too much oil in the water zone. (2) mechanical impurities or coking, causing nozzle clogging. (3) pumps pump failure caused a power outage or disruption to oil. (4) Population oil pump generates ultra-high vaporization, resulting in evacuation pump, oil supply disruption. (5) filter or tubing plug, plug the oil line off the spool, causing the oil pressure drop. (6) cylinder oil level is too low, so that the pump pressure is not oiled. (7) pipeline rupture a serious oil spill, the oil return valve malfunction or suddenly turn up, causing oil plummeted. (8) different oils mixed storage, chemical reaction occurs in the cylinder, could easily lead to precipitation condensation, blocking passage. (9) with wind improper, excessive wind will blow out the fire. (10) The oil temperature is too low, viscosity, oil pump oil into the break. (11) water wall tube burst. 3. gas boiler flame treatment (1) Close the oil valve and run the boiler total nozzle inlet and return valve. (2) to maintain the normal water level of the boiler. (3) to identify the reasons and re-ignition after the fault has been eliminated. (1) oil and gas to the furnace boiler shutdown discharge water, the interior completely remove the dirt and dry with low heat (be careful not to fire), then the lime 10-30 mm block sub-plate installed, placed in a furnace tube do not make contact with metal lime, quicklime weight of 8 kg per cubic meter volume calculations to drum then head holes, hand holes, pipe valve closed, checked every three months, such as lime crumbled into powder, shall Replace the lime and the disc removed fuel gas boiler re-run. Normal operation: fuel gas required to do when the boiler, the boiler water temperature / pressure is normal, supply stability and maintaining the boiler room clean and do shift work, the human factor plays first, to strengthen the observation of various machinery and equipment and instrumentation. Ensure safe and reliable, to prevent accidents, pay attention to saving fuel, fireman should regularly sum up experience, and constantly improve the operational level. Boiler room clean and tidy, bright lights. Boilers and accessories (including pipes, valves, meters) security sensitive and reliable. Shift the two sides to achieve pay thoroughly, then get serious, while the transfer of the situations and problems recorded in the log book. 1. Water requirements: boiler feed water chemical treatment is preferably carried out the pot, water quality should be consistent with GB 1576-2001 "industrial boiler water quality" requirements, the total water hardness less than 0.03mmol / L. See the boiler water quality requirements specified. 2, water supply equipment: run to the pump is normal, when should shift driving test, if the fault repaired immediately. Water containing more or less within the general minerals. Feedwater entering the boiler gasification minerals remain in the pot, and concentrated to a certain extent, to settle down in the boiler, evaporation run for a long time, precipitate, the more, in order to prevent because the scale, slag damage caused by boiler, We must ensure that the water quality, boiler water alkalinity should be no more than 1.25 mEq / l, more than the above range, the response boiler water blowdown. Average user when conditions are not perfect tests, according to the specific circumstances of sewage on a regular basis, such as once a day or once per shift and so on. Frequency is further changed by varying the frequency of the pump speed to change the system of circulating water in the control technology. Frequency control is achieved by changing the frequency of the motor stator power to change the method of its synchronous speed governor. Saving rate is high frequency power-saving technology, almost able to design redundant due to changes in the amount of waste and energy savings all, to overcome the phenomenon of large horse-drawn cart. While reducing mechanical wear and noise, improve the heating quality. To overcome the traditional heating system design cycle power plant due to improper or unreasonable selection, and cause a lot of waste of energy.
