Gas furnace gas steam mass identification of the method for determining the gas quality of a gas steam oven, it must have a manufacturing license manufacturer, the manufacturer must have a manufacturing license, the users must purchase gas pressure temperature set-point efficiency fired steam boiler with production of qualified manufacturers product. See calculation but also the strength and structural design aspects of the gas furnace gas and steam, the furnace is all vapor pressure, and steam oven gas liquid gas into the furnace pressure injection and suction two unpressurized species. Heat Transfer Fluid pressure element whether or not the furnace, it should be calculated according to the current standard boiler intensity calculated geotextile design pressure applied to the working pressure 0.3MPa, and not less than 0.59MPa. Secondly, it is necessary for the steam furnace gas pressure test gas, which when assembled in the manufacturing unit and the unit is mounted in use, a pressure test were performed after repair. Electrically heated gas steam boiler, its pressure test into pressure test, hydraulic pressure test and tightness test. Whether gas furnace electric heating gas or liquid steam boiler furnace, the manufacturing units have to conduct hydrostatic testing, hydraulic test only in the use of the unit, and should not pressure test. For electrically heated gas steam boiler furnace gas, but also in the manufacture of air tightness test unit and used to check the seal of the non-welded joints. Test Method airtight electrically heated gas steam boiler and the requirements of the relevant provisions of the pressure vessel is. For electric heating liquid gas steam boiler furnace, not required tightness test. At the same time, more stringent control of electric welding quality heating gas steam boiler, organic heat carrier due to the electric heating gas steam boiler easy to leakage, flammable, so the electric welding organic heat carrier furnace gas heating boiler steam requirements compared to a medium boiler water is high, the quality of welding should be strictly controlled electrically heated gas 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.

The main difference between the gas boiler and gas pressure temperature set-point efficiency fired steam boiler What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.
