ASTM greenhouse gas fired hot water boiler
How to solve the air pollution problem caused by food processing boiler operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
In the last meeting on April 16, the hard efforts of audits and company officials of president Mr. Lu Haigang couplet review group to pay thanked rigorous review and couplets group work style, professional skills to express my sincere admiration. Ms. Jiang Lianju warranty division said it will continue to improve the ASME quality control system to ensure produce sophisticated products comply with ASME standards. According to ASME certification process, after the on-site audit, the company will obtain certification and stamp issued within 20 working days, this will be the development of our company in the history of another "milestone" event.
Work and family considerations boiler shutdown boiler inspection carried out maintenance before restarting operation, the need for a series of maintenance work, combined with the user experience and learning references, be aware of the following specific boiler maintenance work and family considerations. 1. Preparation (1) before the boiler before the boiler equipment maintenance inspection, as in normal shutdown program is stopped, slow cooling, water circulation and ventilation through the furnace, and gradually lowering the temperature of the boiler furnace. When the temperature dropped below 80 ℃, the door opening open various checks on the boiler. Prevent steam, hot water or cigarette burns when opening the door opening. (2) Steam test boiler feed water, should be separated from the sewer line with the respective other operation of the boiler. Blind for a separator plate should be sufficiently strong to avoid high pressure medium in the broken drum is operated. This clearly indicated the blocking position. Combustion chamber and the flue (3) Check the boiler should be separated from other operation of the boiler. Flue and ventilation doors must be closed tight after separating. 2, preparation of the pressure vessel (1) before the container inspection prior to examination, to be completely cut off the connection tube between the container and the gas pressure or other equipment, particularly equipment using flammable or toxic media. Not only must the valve is closed, and must be sealed with blind plates, so that the valve leaks, resulting in leakage of flammable or toxic gases into the vessel, fire, explosion or poisoning. (2) all media in the container to be discharged. Containers containing flammable, toxic or suffocating medium should be cleaned, replaced or sterilized, by sampling and analysis. A power supply associated with the container, such as a container with a stirrer, reversing mechanism, etc., must be cut off, and a clear flag indicating not allowed to connect. 3, a boiler maintenance considerations are (1) Note ventilation and monitored prior to entering the drum, the container, the drum must be opened, all in the hole hand hole in the container and the collection tank, the air convection period and adequate ventilation. When entering the drum and the container inspection, one must monitor the external device. Before entering the combustion chamber or flue must also be ventilated. (2) Note that the detection of electrical safety in wet flue drum and when the lighting voltage should not exceed 24 volts, with electric lighting. In dry flue, using appropriate security measures, it may be no more than 36 volts lighting voltage. When entering the test vessel, should be used no more than a low-pressure proof lamp voltage 12V or 24V. When the supply voltage detection equipment and maintenance tools than 36V, good insulation must be reliable grounding cord. Boilers and containers should not be used flame. (3) removably connecting member pressing the forbidden band in the inspection of boilers and pressure vessels, pressure if the fastener member needs to unload or screwing, must fully release the pressure, before it can be. Bolts or other fasteners can not be tightened or unloaded at the boiler pressure, in order to prevent accidents. (4) prohibits self-test instead of the hydraulic pressure to the boiler pressure vessel test pressure test generally use water as the pressure medium, there is no gas as a pressure medium, otherwise it is very dangerous. For structural reasons the like, water can not be used as a pressure medium test individual containers, when instead of hydraulic pressure in accordance with design requirements, should be thoroughly checked before the test, check the strength and reliability of the measures taken. Prior to implementation should conscientiously implement the design in accordance with the provisions of, and prior consent of the security sector.
1. 20 tph wns package oil and gas boiler
WNS series gas boiler is a kind of safe and high efficiency(98%) heating equipment with full automatic control system.
