normal pressure fire tube boiler
In early November, the annual "Technology Innovation Award" announced by the Chinese Ministry of Science and Technology Venture Association. Fast Boiler Co., Ltd. With strong R & D strength and strong R & D hardware infrastructure was awarded The "Technology Innovation Award (business)," the honorary title.
Meaning hot water normal pressure fire tube boilers, pressure boilers: 1 pressure hot water boiler, pressure boiler meanings: non-pressure hot water boiler, also called pressure boilers, refers to the top of the boiler through the heating system is not subjected to large static pressure of the water column . That is quite a "open hot water tank." Meaning pressure boiler: boiler body opening to the atmosphere. In any conditions, the boiler at the water line are zero gauge pressure boiler. 2, the principle: 3, models of atmospheric boilers meaning and overall type: Model: The first part of the model by atmospheric pressure boiler code, pot-type code, combustion equipment code, the rated thermal power four sections. Pressure boilers with code "C" represents, for example:. CLSG0.35-95 / 70-W12 represents a vertical pipe fixed grate boiler pressure, the rated thermal power of 0.35 mW, rated outlet water temperature was 95 deg.] C, rated inlet water temperature was 70 ℃, burning anthracite class I, a second design of the boiler. The overall situation: shell boiler (1) vertical water pipe LS (standing water) (2) vertical fire tube LH (flue) (3) vertical heat pipe LR (standing heat)
application of water tube normal pressure fire tube boiler
Because of its structural characteristics and perfect working performance, water tube boilers can produce high-parameter boilers for large and medium-sized factories and power plants.
Advantages of gas-fired steam normal pressure fire tube boiler: 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.
