Horizontal (condensing) oil (gas) steam boiler operation is a dynamic process, from the boiler is opened to the boiler operation process, must always pay attention to the indicators to monitor and adjust the boiler at the right time in order to ensure the normal operation of the boiler, in the boiler operation process the operator must closely monitor the operation of the equipment, and is strictly prohibited from leaving the post for a long time.

Horizontal (condensing) oil (gas) steam boiler in the operation process generally need to monitor the indicators are as follows:

(1) air volume monitoring and regulation. Horizontal (condensing) oil (gas) steam boiler normal operation, generally should maintain a negative pressure of 20 ~ 30Pa chamber, negative pressure is too small, easy to make the flame out, negative pressure is too large, it will draw too much cold air, reduce the temperature of the chamber, increase heat loss. Adjustment of negative pressure in the furnace chamber, the main adjustment of the amount of air supply and induced

Air volume. The amount of air supply and induced draft when the negative pressure of the furnace chamber is small; small amount of air supply and induced draft when the amount of negative pressure of the furnace chamber is large; in order to maintain the negative pressure, in order to increase the amount of air, should first increase the induced draft, and then increase the amount of air supply; in order to reduce the amount of air, should first reduce the amount of air supply, and then reduce the amount of induced draft. Whether the air volume is appropriate, can be observed through the observation mirror to observe the furnace flame and flue gas

The color of the air volume is appropriate, the flame is wheat-yellow (bright yellow), the smoke is gray-white; air volume is too large, the flame is bright and blinding, the smoke is white; air volume is too small, horizontal (condensing) oil (gas) steam boiler flame is dark yellow or dark red.

(2) photoelectric controller monitoring. Horizontal (condensing) oil (gas) steam boiler photoelectric controller to feel the brightness of the interlocking system action, the controller does not enter the normal program, the gas supply solenoid valve will not be opened, the nozzle is not formed at the flame. Therefore, when starting the burner in a bright place, be sure to cover the photoelectric detector with a clean cloth to keep the flame from flaming.

So when starting the burner in the light, be sure to cover the photoelectric detector with a clean cloth, so that it does not see the light, to be sprayed by the burner flame, that is, let go of the photoelectric detector covered, otherwise the burner can not work properly. If the ignition is unsuccessful, no flame is formed, or the photoelectric detector fails to detect the flame brightness, after a safety time of about 23 seconds, the automatic interlocking system will be activated to cut off the burner startup program.

After about 23 seconds of safety time, the automatic interlocking system will be activated to cut off the startup program of the burner and the fault red light will be on.

(3) burner ambient temperature monitoring, control of horizontal (condensing) oil (gas) steam boiler burner ambient temperature, generally should not exceed 70 ℃. Burner use site should avoid stacking flammable, explosive substances and lightweight, floating; items, and strictly avoid foreign objects are sucked into the air ducts causing blockage.

(4) Monitor the water level of the horizontal (condensing) oil (gas) steam boiler to prevent water diffusion. When the water level is higher than the maximum permissible line, or invisible water level, water level meter glass tube (plate) in the color dark, two-color water level meter is all water phase indication color, control panel water level very high alarm signal, sub-cylinder a large number of water, hydrophobic    

   Drainer

   Drastic action, the boiler is full of water, then, you should first close the water level meter, the water pipe plug, and then open the drain plug, such as the water level line can be seen falling from the top, indicating that it is slightly full of water, stop the water supply, open the drain valve, put to the normal water level. If seriously full of water, due to take emergency measures to stop the furnace, if necessary, should be    

   Shut down the furnace boiler water hammer accident.

(5) Boiler water hammer. In the horizontal (condensing) oil (gas) steam boiler and piping at a certain rhythmic impact sound, sometimes loud, accompanied by strong vibration of the feed pipe or steam piping. The pressure gauge pointer swings back and forth, consistent with the frequency of the vibration of the ringing sound. When water hammer is severe, it may lead to the connection of various

   parts, such as flanges, weld cracks, broken valves, etc.. At this time, you should reduce the steam supply, open the steam trap on the pipeline for trapping, proper drainage, maintain normal water level, increase the number of times of drainage, to ensure that the quality of feed water and pot water, to avoid the occurrence of steam and water co-existing.

(6) pressure controller. Steam pressure is horizontal (condensing) oil (gas) steam boiler safe operation of one of the main parameters, but also an important indicator of steam quality. Pressure controller will be converted into electrical signals pressure signal electromechanical conversion device, its function will be high and low pressure signals to the electrical switch.

   Different boiler pressure indicators may be different, gas steam boiler steam pressure regulation is to try to maintain the balance between the gas steam boiler steam production and external steam consumption, control the steam supply pressure is stable within the prescribed range. Steam pressure control and regulation to change the gas steam boiler steam production as a means of regulation.    

   Paragraph, the size of the gas steam boiler steam production is determined by the gas steam boiler operator on the combustion of the regulation, that is, the amount of coal, air supply, the pot water level and combustion of the regulation of the state when the load increases the vapor pressure drops, this time should be adjusted according to the actual water level of the gas steam boiler. If the water

   If the water level is high, you should first reduce the amount of water or suspend the water supply, and then increase the amount of coal and air supply, strengthen the combustion to improve evaporation to meet the load needs, so that the vapor pressure and water level stabilized in the prescribed range. Then adjust the combustion and water supply according to normal conditions. If the water level is low, should first increase the horizontal (condensing) fuel oil

   (gas) steam boiler should first increase the horizontal (condensing) oil (gas) steam boiler to the amount of coal and air supply, while strengthening the combustion, gradually increase the amount of water to maintain the horizontal (condensing) oil (gas) steam boiler vapor pressure and water level normal.

Horizontal (condensing) oil (gas) steam boilers in operation need to monitor more than the above indicators, boiler production technology and automation technology is changing day by day, customers can choose the boiler in the choice of boiler intelligent control of the boiler, reduce boiler maintenance of labor costs.
