Eco-friendly gas fired steam boiler
In order to ensure boiler safety, to run smoothly, you must ensure that the use of high-quality natural gas. 1, equipped with one gas separator to increase the capacity, it can effectively store oil and water. Secondly, a level gauge designed to directly observe whether there is liquid in the separator. While the design of the automatic drain pressure relief device is installed. A single control pressure of the air is improved dual control, i.e. the pressure regulating valve is mounted on the main line to control the water separator, the pressure to stabilize, improve security purposes. 2, safety monitoring natural gas as a boiler room burning materials, natural gas leak monitoring must be done. The portable display technology poor performance, poor sensitivity. Host combustible gas alarm system with digital control scaling circuit having an alarm function and a secondary alarm, ensure the safe operation of the boiler. 3, check before firing the safe operation of: (1) whether the boiler inspection gates normally open or closed, check the gas pressure is normal, not too high or too low, open the supply valve leading to the boiler. (2) in the flue baffle must be fully open, otherwise it will affect the purge, causing accidents. Each knob and keep control cabinet to check the normal position. If the stove has a residue should be cleaned. (5) Check the boiler ignition and fire protection program control means should be flexible and reliable. Blast doors should be flexible and rigorous on the boiler. Before the completion of ignition, the ignition is not possible to start the ignition operation: After successful ignition, the load can be adjusted in the normal operation of the boiler when the combustion gas boiler adjusted. We should always observe the combustion furnace, and adjust the amount of steam, wind and steam pressure to ensure the safe operation of the boiler. Note: Program: first five minutes were furnace cleaning, automatic ignition after 5 minutes, observe the ignition is successful, the success of one minute after a small fire can be operated automatically converted to fire properly. For the boiler load and the air pressure adjusted by adjusting the pressure regulator to achieve. When adjusting the load, adjust the air pressure at the same time, it must be synchronized to adjust the air flow to ensure a reasonable match air volume and air volume, in order to achieve economic operation of the boiler. In normal operation, the amount of gas should not be adjusted or reduced drastically in order to avoid dramatic changes in combustion, the pressure receiving member sudden expansion, shrinkage and damage. When the boiler is running, the pressure gauge must be monitored regularly in order to maintain stable water pressure. BCP pressure changes observed, reflecting the relationship between water temperature and steam consumption. In the boiler operation, when the steam pressure is automatically adjusted, the main purpose of the staff is to monitor automatically adjusts the boiler system is sensitive and timely solutions to problems and ensure the sensitivity and reliability of the automatic control system. 4, first close the main valve shutdown operation, the air supply is stopped, the circulating pump and the water pump is still running, when the boiler water temperature falls below 70, and supplies or stops the circulation pump in operation of the pump after about 4 hours. Note: In addition to the accident and emergency parking stop, parking general approach should not cut off the power. After the shutdown, it is timely for the boiler and ancillary equipment to conduct a comprehensive inspection. If you find a defect in the device, and repair should be recorded at the time of shutdown. Safety Precautions 1. burner startup, if the burner is repeatedly locking and alarm, you should find out the cause of the malfunction, press the reset button after troubleshooting, press the reset button and then continue to boot. Note: Press the Reset button for less than 10 seconds. A lower burner inlet must be clean and clean, and does not allow offal. 2. burner once the ignition is unsuccessful, Boiler Fan should be restarted. Ventilation After 5 minutes, start the second startup burner igniter. three. During normal operation, the thermal device near the burner portion (e.g. flange connections) will be very hot, in order to avoid burns. Do not put flammable materials in the vicinity so as not to cause a fire. 4. The operation of the boiler circulating pump must be closely monitored and the hot water boiler pressure, gas distributor, pipeline valves, pressure gauges, flow meters, water level gauge and the like. 5. When the firefighters open the door or fire door observation, you should wear gloves and a side view. 6. A burner working environment should be kept clean and dry, in particular, a flame detector (i.e. electric eye) should be kept clean, part of the control circuit should humidity and temperature; class should cleaning and maintenance of a combustor. 7. During use, the filter should be cleaned regularly check or replace the filter cartridge in accordance with impurities of the fuel. 8. Check the electrical installations include: wire is damaged, the sheath is damaged, the screw is loose, the contact is good, whether the motor is running abnormal noise. Describes the advantages and disadvantages of natural gas boiler, editor of Sin sets introduced, the use of technology and safety precautions. Industrial boilers to energy efficient, environmentally friendly development direction. Natural gas boiler to meet the needs of these three points. They are the future of the boiler market trend, more and more restricted energy policy, energy saving and environmental protection requirements.
To introduce eco-friendly fired steam boiler pressure gauge and hydraulic press accumulator using steam boiler pressure gauge should pay attention to: 1, rated steam pressure is less than 2.45MPa steam boiler, the accuracy of pressure gauge must not be 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The diameter of the dial of the pressure gauge shall not be less than 100 mm to ensure that the operator can see clearly the surface pressure indicator value. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. Steam boiler pressure gauges should be installed in a place that is easy to observe and wash. 4. Steam boiler pressure gauges should be checked at least once every six months, and should be sealed with lead after calibration. 5. Steam boiler pressure gauges should not have leakage of water and steam leakage in the connecting tubes of the pressure gauges of steam boilers. (4) the steam boiler pressure gauges should be checked at least once every six months and sealed with lead. 5. Otherwise, the pressure indicator value will be reduced. 6. The measurement range of the steam boiler pressure gauge should be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have pressure gauge, the pressure gauge is damaged or the installation of pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following conditions: 1, broken surface glass or dial calibration mold There is no clear paste; 2, no lead seal, lead seal damage or beyond the calibration period; 3, without pressure, the pressure gauge of the finite pin can not be restored to the limit pin, the infinite position of the gauge pointer deviated from zero data beyond the allowable pressure clothing; 4, gas leakage or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge. Purpose of the accumulator: the accumulator is used in the hydraulic system of intermittent machinery, which stores the oil output of the hydraulic pump during intermittent or low-speed movement of the actuator, and when the rapid movement of the actuator requires a large flow rate, As an auxiliary energy source, together with the hydraulic pump, the oil pump is supplied to the system, thus the oil pump and the hydraulic pump are realized. The miniaturization of the whole hydraulic device absorbs the quick opening and closing of the impact hydraulic reversing valve and the sudden change of the load. The system will produce shock pressure, the darling will lead to vibration and noise, and even damage the machine. The accumulator can mitigate the impact pressure absorption pulsation of these fluids absorb and reduce the flow pulsation and pressure pulsation of various hydraulic pumps thus reducing the system noise and vibration. The damped accumulator acts as a gas spring and can be used to absorb the vibration between the fuselage and wheels of walking machinery such as vehicles. The balanced accumulator absorbs the gravitational potential energy of the vertical actuator (hydraulic cylinder) and its load as it falls. When the vertical actuator rises, the accumulator releases the original absorbed energy and supplies oil to the hydraulic cylinder together with the pump, thus realizing the balance and energy saving.
The main function is to ensure that the monitoring system burner safe and stable operation, the main components are: flame detectors, pressure monitors, temperature monitors and the like. Flame detector: monitoring conditions for forming the flame, and generates a signal reporting programmer. There are three main flame monitoring: photosensitive resistance, electric eye UV ultraviolet, ionizing electrode.
