Check Item item dzl coal fired 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.

Layer burning coal combustion boiler, the coal through the coal chain grate conveyor plane, the complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. 2. Combustion of Coal mainly by c, H, s, 0, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound. Coal combustion heat release, and smoke into the atmosphere by the SO²SO³NOx generated, environmental pollution, harm to humans the main component of natural gas is methane (CH.) Gas, and a small amount of non-hydrocarbon gases. Generally free of moisture and ash after the combustion of natural gas, produce mainly water co2 and emit a lot of heat, deleterious SO2, SO3Nox other emissions is relatively much less coal.

Natural gas steam boiler by what configuration consisting of environmental policy and natural gas high pressure steam boiler their good performance advantages, let natural gas steam boiler stand out in a crowd boiler types, all ages, and use more and more users. Many users before purchase natural gas steam boiler, the boiler due to insufficient understanding, very easy to be deceived poor sales. Today we have to say something about, what are the natural gas steam boiler configuration consisting of it so that we have a general concept. Natural gas steam boiler is a series of devices can be roughly divided into two main parts and auxiliary equipment. First, the main member 1, the chamber: the fuel burn-up and ensures that the boiler outlet temperature of the flue gas is cooled to a value of convection heating surface capable of security. 2, the drum: the respective heating surface and joined together and the boiler water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. 3, water wall: mainly radiation heating surface of the boiler, the absorption of radiant heat furnace heated working fluid to protect the furnace wall and the like. 4, combustion equipment: the fuel and air required for combustion of the fuel into the furnace ignition and stable good combustion. 5, air preheater: heating the fuel with air, in order to enhance ignition and combustion; flue gas waste heat absorption, reducing the exhaust gas temperature, increase boiler efficiency. 6, the furnace walls: a housing to protect the boiler, since sealing and insulation. Heavy furnace wall of the small boiler may also function as a support member boiler. 7, the frame: a support member and fixing the boiler. Second, the auxiliary device 1, the wind equipment: induced draft fan and chimney via the flue gas generated in boiler operation sent to the atmosphere. 2, dust removal equipment: removing fly ash in the boiler flue gas. 3, the fuel supply apparatus: fuel storage and transportation work 4, water supply equipment: a water pump to feed water through the water treatment device into the boiler. 5, the air blowing apparatus: the air blower means through application exports the furnace air preheater and a coal grinding heat. 6, the automatic control device: automatic detection, process control, automatic protection and automatic adjustment. Natural gas steam boiler is mainly from these major components and auxiliary equipment components, making them a reasonable match to achieve efficient boilers, environmental effects, but also improve the thermal efficiency of the boiler, the boiler at work so that you can achieve safe and reliable results.

Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton ​​steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
