Flue gas fuel steam high pressure boiler 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.
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 steam high pressure 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.
How the choice of steam steam high pressure boilers should distinguish quality? Market top quality steam boilers are very different, so the user selects this product, it needs to identify its quality, then how to distinguish the quality of this product do? First a quality product from the main body of the boiler, it is necessary to identify the quality of the user through the body of the boiler. Body using what kind of material, and what kind of welding process, etc., the details of which are to be noted, that if the boiler has not reached a corresponding requirements in the above welding, when the fire will drain the user . If the material does not meet the corresponding requirements, it is difficult to meet the requirements of thermal insulation.
The presence of boiler scale is equivalent to an additional layer of resistance heating surface, because the scale is lower than the thermal conductivity of steel is large, hindering heat transfer, the heat released by combustion of fuel can not be effectively transferred to the water, water vapor can not be measured heat , with the exhaust gas side of heat is lost, and therefore to reduce the boiler output, fuel waste. According to statistics, the junction of a millimeter scale, about 2 to 3% waste fuel.

The advances in steam pressure and temperature led to the development of the reheat cycle, where steam is exhausted from the high-pressure turbine at reduced pressure and temperature and is then returned either to a section of the boiler or to a separate boiler to be reheated. Once reheated, the steam is sent to the low-pressure boiler.Get A Quote
