Condensing gas boiler advantages of food plants have small module which utility model volume, no backup boiler, save space, improve space utilization. Gas furnace modules each module operate independently when a single unit fails, does not affect the operation of the entire system. It is no backup boiler. It covers an area of ​​small, can be installed in the basement and other small equipment room. Reduce boiler room investment costs and improve the site utilization. High efficiency gas module, operating cost savings of gas. After a transfer, high temperature flue gas in the flue gas temperature is still high after complete combustion. When the second heat transfer zone through, since the return water temperature is low, the high temperature flue gas when it encounters a low temperature the water vapor will condense into water tube wall, releasing large amounts of heat. After absorbing heat in the flue gas temperature, flue gas temperature will be greatly reduced, thereby reducing heat loss, the thermal efficiency of 107.5%. 5000 square meters of heated area for example. For the 200-room hotel, the heating season may not only save heating costs 1,100 yuan, but it will save 800-1200 yuan of hot water. This project only saves gas cost about 20,000 yuan, reflecting the economy and efficiency of the module condensable gas stove to save on gas energy.

The competition, the segment is slowly 45 contestants only a female welder, most of the other competitors from China Electric Power Construction, veteran welders in the petroleum, petrochemical, and other large number of country prefix units, with a very rich practical operation of work experience. Faced with numerous welding expert, slowly segment did not flinch and fear, but to actively exercise their welding ability, the old master who humbly ask to try a variety of different welding methods, and repeat the training to do practice makes perfect. By her welded boiler parts forming the United States, no weld defects neat; in her station, welding clean, neatly stacked tools, work order. It is because of her usual work down to earth, hard work and practice, lay a solid foundation for the success obtained.

China is now the standard content of nitrogen oxides are mainly three: 150mg / m³, 80mg / m³ and 3mg / m³. The nitrogen oxide content of the conventional gas boiler is about 150mg, and emissions of 30mg and 80mg belong to a low nitrogen gas boiler. Adding "premix" combustion gas boiler technology can achieve low nitrogen emissions.

While the purge of the boiler furnace and flue is a certain flow velocity of the air with. Case 3, in the rear of the boiler did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case.

4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, it is necessary to detect smoke components, to avoid too high excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.

5, real-time attention should fireman switch case of a gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valves, only put into operation is determined normal.

6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion.

7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close air release valve.

8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, should contact the gas company. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter.

9, should comply boiler unit boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. When there are unusual circumstances and can not solve the problem, depending on the nature of the problem promptly contact boiler plant or gas company, to conduct maintenance by a professional maintenance staff.
