Fuel oil-fired 3t h corn valve shaft used boiler boiler water filling operation process in preparation for the next cold case into operation, we must first understand the boiler water filling system without fault, and therefore should be done before firing boiler water filling trials to test boiler water filling system is normal, pipeline The valve leaks. Operating Procedure: (1) upon inspection of boiler meet the operational requirements, in order to carry out work in Sheung Shui boilers; before (2) Sheung Shui, you must get in touch with the boiler water quality testing staff to ensure that water treatment is working properly, to avoid affecting the boiler water filling; (3) open the power, boiler exhaust valve opening, to start the pump, check the boiler water pressure greater than the working pressure, to open the valve, to boiler Feed; (4) fuel boiler Feed simultaneously, open the drain valve drainage , the inner opening the drain valve, the drain valve opened outward, outer closed drain valve, the drain valve closed inner, outer 2nd opening the drain valve, 2nd outer drain valve closed, after rinsing pot, close the drain valve to continue on to the boiler water; (5) the pot water level reaches the normal level, to turn off the water supply pump is stopped, the exhaust valves; (6) for water drainage test table, the drain valve open water table, the water table confirm normal, closed drainage water table valve, waiting for ignition. Sheung Shui operational matters should be noted: Sheung Shui to oil-fired boiler water level should not exceed the normal water level, because when the boiler ignition, the boiler thermal expansion of water, the water level rise would exceed the maximum safe water level. If this happens, the water level should be adjusted by sewage.
Factors affecting the thermal efficiency of gas 3t h corn valve shaft used boilers What?
1, exhaust gas temperature: the temperature of exhaust gas boiler is generally increased by 15 degrees, heat losses will be increased by 1%.
2, the oxygen content of the furnace: the excess air factor, when an excessive increase in heat losses, is too small incomplete combustion loss increases.
3, furnace pressure: positive pressure when the furnace operating conditions reasonable time, can effectively avoid the intrusion of the cold hearth, a negative pressure may increase the air ratio to increase the exhaust loss;
4, insulation factor: This factor is mostly caused by maintenance when the boiler is located somewhere inside the pieces of insulation failure, repair the insulation layer must be removed, after the repair is completed insulation can not be repaired, resulting in an increase boiler thermal dissipation loss.
installation price and advantage of electric 3t h corn valve shaft used boiler
There are many advantages of electric boiler. It is an economical, energy-saving, safe, scientific, environmental-friendly, emerging, and efficient heating way to increase the number of users of electric boiler. With the combination of electric boiler and ground heating system, room temperature decreases gradually from bottom to top, giving people the feeling of cold feet. Improve blood circulation, promote new town metabolism, has a certain health care effect. In line with the "warm from the foot, ten thousand cold at the foot of" the principle of traditional Chinese medicine. Electric boiler work without any odor, noise, no electronic radiation.
