China circulating fluidized bed boiler supplies

What should we pay attention to when using Atmospheric pressure Hot Water Boiler

Since 1970s, atmospheric hot water boilers have been widely used in China, especially in northern China. It is popular not only because of its low cost, easy manufacturing, but also because it has the characteristics of simple management, safe operation and so on. Precisely because atmospheric pressure hot water boilers have been widely used in various industries, it is particularly important to pay attention to its use, especially for new adopters, the following points should be paid more attention to: 1. The pipe diameter of atmospheric hot water boiler is the same as that of atmosphere. Under any working condition, the water mark of boiler is in the boiler with zero surface pressure. So before you use it, the user The new boiler should be inspected, especially if the diameter of the pipe meets the requirements. In addition, any valves should be strictly prohibited on the connecting pipe to ensure that the pipe is unobstructed. In general, the specialized atmospheric hot water boiler will also spray on the furnace body obvious position "the normal pressure boiler shall not be used under pressure and the outlet hot water temperature shall not exceed 90 ℃".

2. professional installation, commissioning when the first purchase of hot water boiler manufacturers will recommend that the installation and commissioning of the boiler is responsible for the professional personnel. Once put into use, non-professionals are not allowed to change the boiler structure, install system lines, valves at will. At the same time, attention should also be paid to the conversion of atmospheric hot water boilers into pressure boilers.

3. to ensure the boiler safety accessories sensitive and reliable long-term use of atmospheric hot water boilers know that regular fixed-point pressure gauges and thermometers should be professionally verified to ensure that the calibration is used within the validity period. In addition, in order to ensure the safety, sensitivity and reliability of the boiler, the operator should often flush the water level meter and check the temperature and water level control device. In the course of boiler operation, the operator should pay attention to the changes inside and outside the boiler in time to ensure the safety.

Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water china circulating fluidized bed boiler supplies of 2.1MW.

2, a number of insulation measures to prevent heat loss

Side using fast excellent ultra-thin insulation effect as cotton glass furnace insulation materials, before and after the smoke box of the aluminum plates as a selected temperature insulation material; and the whole was sealed boiler structure, no air leakage, the weld phenomenon is not tight, boiler to reduce heat loss to a great extent.

Flue gas fuel china circulating fluidized bed boiler supplies design requirements fuel gas boiler flue design requirements: 1. The flue should be straight, air tightness, attachment and less and less resistance, more than 1% level to maintain the flue should rise laying layout, try to avoid Longitudinal arrangement. 2. Fuel gas-fired boiler house and chimney flue should be constructed of steel or reinforced concrete, the lowest point of the flue and chimney should be set to seal air-conditioners, water drains. The thickness of the metal sheet 3. The flue generally use 4 ~ 6mm, the flue design, should be sufficient arranged reinforcing ribs to ensure the strength and stiffness requirements. 4. The thermal expansion of the flue should be compensated, the compensation amount to be calculated and the correct selection. The steel flue insulation measures should be reliable and fixed. 6. The fuel gas boiler corresponds to a boiler should be a chimney, when required by the conditions a boiler flue or chimney common to several units, each boiler should be ventilated suction force balance. 7. The flue should be arranged to set the necessary thermal and environmental measuring point measuring point in place. Single rated evaporation amount is equal to 20t / h or single thermal rating of greater than or equal 14MW oil-fired boiler, a fixed continuous monitoring must be installed in the flue gas dust, SO2 emission concentration instrument. 8. In the flue gas gathering place easily and when many boilers a share or a total chimney flue shall be fitted with explosion-proof door on the flue after each fuel gas-fired boiler, the location of the vent should be conducive to relief, It should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator that should be installed on the guide tube explosion relief means. 9. For some longer flue boiler room, they should be accounted for resistance, select the appropriate blower, Fan (when there is draft fan), to ensure the smooth flow of exhaust. 10. The chimney should be considered appropriate anti-corrosion measures, chimney flue gas outlet temperature is preferably above the dew point of the flue gas temperature of 15 deg.] C; when the exhaust gas temperature is lower than the dew point temperature of flue gas, the flue gas should take effective measures to prevent the intrusion.
