Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.

The central heating boiler is especially suitable for schools, department, hotels, public bathhouse and such projects with hot water supplies. Our boiler forheatingare mainly WNS oil & gas fired boiler, coal fired boiler, biomass fired boiler etc. The fuels of oil & gas fired boiler shall be natural gas, city gas, LPG, methane, methane, ethanol and other flammable gases, light oil, diesel etc. And the biomass fuels shall be rice husk, peanut shells, bark, sawdust, bagasse, coconut shells, straw etc. All these boilers are quite economy, but people prefer oil gas fired boiler and biomass fired boiler due to the environment protection policies.

Check Item item coal for hot water boiler hot water boiler comprising a boiler inspection and checking internal use preparations, checking in the furnace and the flue, the boiler attachment check, check automatic control system, the secondary device, check the combustion device, the auxiliary heat check the surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling. It is fed out of the hot water boiler heat equivalent to a mass per hour (usually expressed in tons) in water was heated from 20 ℃ and heat output of all vaporized into a steam boiler water absorbed three expressions, in tons) water from 20 ℃ heated and vaporized into all heat absorbed by the steam boiler it is fed out of the hot water heat equivalent to a mass per hour (i.e. typically kcal / hr (kcal / h), tonnes / hour (t / h ), megawatt (MW). (1) kcal / h is in metric units of expression, which represents the heat of hot water boiler fed out per hour. (2) t t borrowed steamed steam boiler popular argument, ( 3) megawatts (MW) is the international system of units unit of power, the basic unit is W (1MW = 106W). this expression formal documents should be used.

Efficiency Efficiency boiler fuel oil-fired boiler (1) and the threaded pipe arch tube plate consisting drum, the drum so that a quasi rigid body variant subject elastomeric structure, the bracing member canceled tube sheet area, reducing stress. Smoke tube consists of two single backhaul backhaul to solve the problem of cracking of the tube plate. (2) a lower drum rise due to the arrangement of the discharge tube, eliminating dead zones at the bottom of the drum, so that there is less deposit sludge, drum high temperature region can be obtained good cooling, preventing the lower portion of the boiler drum package boiler shell. (3) use of efficient heat transfer threaded pipe, the heat transfer enhancement effect is obtained, heating the boiler to reach fast boosting features improve the thermal efficiency of the boiler. (4) stable, easy adjustment, contribute enough. It has 110% overload capacity. (5) coal for hot water boilers have been major improvements in the water cycle. Successful use of jet technology, the purpose of the return water jet enters the downcomer, to improve the cycle rate of the riser. (6) The threaded pipe enhanced heat transfer, the heat transfer coefficient and improve thermal efficiency, since there is disturbance in the flue gas pipe, hard fouling smoke tube, play a role in self-cleaning. (7) use of energy efficient furnace furnace arch integrally cast heat resistant concrete, improved coal fire conditions, uses a separate plenum, to achieve reasonable air distribution, forming a favorable aerodynamic field of combustion in the furnace, whereby expand the adaptability of coal. Furnace arch (8) of the boiler, there is a certain part of the outlet smoke dust window effect. The original boiler control dust emission concentrations below the standard, to ensure that the indicators boiler soot emissions meet the national environmental regulations.
