6 ton hot water boiler manufacturers
Gas 6 ton hot water boiler manufacturers maintenance during the shutdown as we all know, the heating of the heating unit in our country is from October 15 to April 15, the six-month heating season the north, in industrial production, gas hot water boiler is only used winter heating. After the winter heating season, the hot water boiler will be idle. To ensure the normal operation of the hot water boiler next year, can not relax to maintain idle period. 1. When idle, the boiler water is discharged and should be placed in a ventilated place. Second, the hot water boiler furnace repair cracks need to find specialized personnel to repair, if necessary, be coated with an external lubricating furnace or anti-corrosion paint. three. Different methods and disintegration downtime 1, boiler water drained, draining suction process when the boiler is shut down three days or less, ammonia and hydrazine before shutdown, feedwater PH value to 10 or more, and then a certain pressure the drainage furnace, keep the system dry. 2, the film formation method when the amine protecting the furnace off over three days, the protective effect of the film formation is preferably an amine, such as pure octadecylamine protection, i.e., protection of octadecylamine was added a solution of pure water vapor in the system before the oven is turned off. 4. Different methods used during the non-disintegration of the stop 1 and, maintaining the gas hot water boiler pressure method: discontinued within 1Od, discontinued before increasing ammonia, hydrazine dosage of the feed water to raise the pH above 10, to maintain the boiler pressure. 2, gas protection law: if the operation is suspended for more than 10 days may be by gas protection method for long-term protection of the boiler. Fifth, the gas hot water boiler maintenance boiler off Desiccant method, the boiler water temperature dropped to 100-120 (?) All C is discharged, the water in the furnace, the metal surface of the dry heat boiler, the system scale, slag all clean, and a desiccant to keep dry the metal surface, to prevent corrosion.
Nongfu Spring has been committed to the production of natural and healthy drinking water, only after a simple filtration, without changing the water quality, maintain natural water features indicators, unswervingly follow the environmental, health, natural path of development. Fast boiler since its inception, focused on research and development of clean boiler design, adhere to the concept of environmental protection has become condensing gas boiler industry leader. The same faith, the same dedication to promote fast boiler and Nongfu Spring work together to create new environmental future.
Common feature D, A-type and O-type boiler is: horizontal burner installation, operation and maintenance more convenient; wide, high small size, arranged in the longitudinal direction of the heating surface has a great margin, facilitate quick, production can be assembled.
Flue gas fuel boiler design requirements 1) to be straight flue, air tightness, attachment and less resistance is small, the level of 1% or more to maintain the flue rise should be disposed laying down slope disposed avoided. 2) the fuel gas flue and the chimney of the boiler should be of steel or reinforced concrete construction, the lowest point of the flue and the chimney should be water-seal disposed condensate drains. 3) thickness of the metal plate is generally used flue 4 ~ 6mm, the flue design, should be sufficient arranged reinforcing ribs to ensure the strength and stiffness requirements. 4) thermal expansion of the flue should be compensated, the compensation amount to be calculated and the correct selection. 5) steel flue and reliable insulation measures should be fixed. 6) a fuel gas boiler should correspond to a chimney boiler, when the boiler by the conditions required to share a chimney flue or several, each boiler should be ventilated suction force balance. 7) arranged in a flue provided when 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 smoke flue gas must be installed. S02 emission concentration of the instrument. 8) Where the flue gas is easy to assemble, and when more than one boiler or a total share a 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, should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator, should be installed on the guide tube explosion relief means. 9) For some of the longer flue boiler room, they should be accounted for resistance, select the corresponding drum, induced draft fan (ID fan when there), in order to ensure the smooth flow of exhaust. 10) should be considered appropriate chimney 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.
