boiler efficiency curve

In recent years, Hebei Province People's Government to respond positively to Blue Sky Battle action plan promulgated by the state, and all of 35t / h coal-fired boiler efficiency curve and below in the Hebei province out of the transformation process. First Hospital of Baoding respond positively to the call of the provincial government, eliminate serious pollution of the original coal-fired boiler hospital, citing energy saving steam boiler to natural gas as raw material. After a series of market research, WNS Series Split hospital condensing gas boiler boiler other fast soft spot.

Advantages of gas-fired steam boiler efficiency curve: with the designer re-design machinery innovation, the operation of the equipment is simple and convenient. Gas-fired steam boiler is not only easy to operate, but also better to ensure the safety of operation. Energy-saving advantage: gas-fired steam boiler has the characteristics of high temperature and low pressure, which greatly reduces the operating pressure level of heating equipment and benefits directly from the reduction of equipment investment. Also said the ratio of raw material to air contact. Only proper amount of fuel and proper amount of air can form combustion ratio in order to achieve combustion efficiency. At the same time, it can reduce gas emission, achieve double energy saving, and is very convenient. The gas-fired steam boiler can be used according to the actual need for steam. The quantity is equipped, can reduce the energy waste. The higher the match between the actual demand and the theoretical supply, the better the energy saving effect. Heat exchange can increase the feed water temperature of deaerated water by utilizing the heat discharged from the water continuously. Mechanical equipment, such as gas-fired boilers, is more widely used in accordance with the requirements of today's environmentally friendly uses. In serious cases, steam is seriously watered, salt content of small gas-fired steam boiler increases, water hammer makes sound in steam pipe, steam drips outward at connecting flange; If the furnace tube or economizer pipe breaks, the feed water flow rate is less than the steam flow rate, when the water shortage occurs, there will be the opposite. When water shortage is severe, red hot water wall pipes can be seen from the furnace door, and the smell of coke can also be smelled. At the same time, the furnace tube may break, the explosion can be heard. Steam and smoke will be discharged from the fire doors and fire doors. The low water level interlock device, if the water level is below the specified value, the blower, the induced draft fan and the furnace row deceleration motor shall stop running, the water level is lower than the low safety water level line, the water level glass tube (plate) is white; Does the flushing water gauge determine whether a small gas steam pan is slightly or severely filled with water? Methods: first turn off the water level meter, water connection pipe cock, and then open the drain cock. If you can To see the level line drop from the top, it is slightly filled with water, opening the drain valve and placing it at the normal level. If the water is seriously filled, please take emergency shutdown measures.

Third, regular inspections

Boiler having a certain pressure, because of the pressure, which can produce a high temperature well above 100 deg.] C, high-quality steam. But the pressure will have a certain risk, China has a dedicated quality control monitoring boiler inspection department, quality inspection once a year for the boiler, in order to ensure its good safety performance.
