hot water boiler for power plant

Gas-fired steam boiler overpressure fault Introduction and approach: 1, boiler overpressure phenomenon of a sharp increase in vapor pressure, exceeds the allowable operating pressure, the safety valve pressure gauge pointer over the red line pressure is still elevated. b. When the interlock operation overpressure protection device, an alarm should be issued overpressure signal to stop the air blowing, the wind, coal. C. steam temperature and steam flow rate reduction increases. 2, boiler overpressure of emergency a. Weakened rapidly burning, manually open the valve or bleed valve. B. to increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. c. If the safety valve pressure gauge malfunction or all of the damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. D. When the boiler and endanger the safe operation excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. e. When the boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and repair failed.

Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube steam boiler (SZS25-2.0-YQ).

Routine maintenance routine maintenance process gas boiler gas boiler gas boiler can be divided into two parts: preparation and running before the start of the examination. Before starting to prepare: 1. Check the air pressure is normal, the valve leaks, the switching valve is in place. 2. The gas alarm system is tested to determine if it can work, and if the fan can be started. three. Check the water softening system. Softener should be in working condition, the tank level should be normal. 4. Check valve switch boiler and decontamination work. The circulation pump outlet valve closed, to start the circulation pump, slowly open the water outlet valve, the outlet pressure is adjusted to 0.3 ~ 0.35mpa, and the pressure is adjusted to reflux for 0.2 ~ 0.25mpa. Running check: 1. Open the power boiler, the boiler normal ignition operation monitoring, checking and each member state of the flame sound. 2. The heating boiler operating conditions can not be ignored, large and small units commutation control conditions should be normal. 4, the temperature difference of each recording circuit water, the water supply valve to adjust the return water temperature by two hours the water pressure and temperature recording every each circuit. 5. After checking the boiler pressure, temperature anomalies, should be stopped and checked. 6. Check the gas flow and gas pressure stability is within the normal range, to determine whether there is clogging the filter. 7. Check the pressure pump to see if there is abnormal noise and other anomalies.
