100kg natural gas steam boiler for railway
To continue to improve air quality and protect people's lives and health, Hainan Province, issued a "Hainan Air Pollution Prevention Regulations" (hereinafter referred to as "Regulations"), a clear implementation of the total coal consumption control system, and gradually reduce the amount of coal consumption, phase out existing coal-fired units. "Regulations" since March 1, 2019 into effect.
"Regulations" put forward specific requirements for coal and other energy pollution control.
A prohibited import, sale and burning of coal does not meet quality standards; prohibited the import, sales do not meet standards of quality petroleum coke; prohibition of burning petroleum coke. Above the county level department in charge of market supervision and management need to be strengthened coal, petroleum coke quality management, from time to time on coal, petroleum coke quality sampling.
Second, the people's government above the county level market supervision and administration departments shall, jointly with relevant departments in charge of the environment, industry and information technology, etc. According to China's Hainan Province and the relevant provisions to strengthen the supervision and management of boiler production, import, sale, use, etc., do not compliance with environmental standards or requirements shall not manufacture, import, sale and use. Phasing out coal-fired boilers. Existing clean energy such as natural gas-fired boilers, furnaces, low NOx combustion should be completed within the prescribed period of transformation of the people's governments above the county level department in charge of the ecological environment. New clean energy such as natural gas-fired boilers, furnaces and other facilities shall pollution control measures such as the use of low NOx combustion.
Third, the central heating has been implemented for the work (production) business park, a ban on new construction, renovation, expansion of decentralized heating boilers, heating boilers should be dispersed in the original city, county, autonomous county people's government department in charge of market supervision prescribed period in the demolition; work not yet implemented central heating (production) business park has heating demand should be in the city, county, central heating implementation as soon as possible within the time limit prescribed Autonomous County people's government department in charge of market supervision and management, and removal of the original dispersion heating boilers.
Corner tube 100kg steam boiler for railway is one type of chain grate steam boiler. ZG manufactured corner tube biomass fired steam boiler’s power is among 6 to 15 MW. This biomass fired steam boiler adopts corner tube pattern, self-supporting structure. The furnace and the descending fuel gas duct adopts total welding membrane water cool tubes wall structure, which has benefits of good sealing, lower heat reducing. Both air pre-heater and economizer adopt case pattern structure which is convenient to transport and install. As a top steam boiler manufacturer in China, our single drum corner tube biomass fired steam boiler made in China is both eco-friendly and high efficiency.
2.4MW YQW series gas-fired horizontal thermal oil heater for food industryChongqing Sanyi Food Co., Ltd. is a modern food enterprise engaged in the production and sales of hot pot butter products and hotpot seasonings. Sanyi Food combines the second generation technology of advanced "physical high temperature deacidification" with the traditional process, in which the stable heat source provided by the boiler meets the high temperature requirements of the production line.As the products sell well, Sanyi Food has built a modern comprehensive production base of more than 20,000 square meters in 2016, which adopted advanced automated production lines, and it was urgent to introduce energy-efficient boilers and use clean energy natural gas as fuel. ZOZEN became the boiler supplier of Sanyi Food due to its outstanding advantages in product performance and environmental protection effects. In order to meet the different requirements of the production line for temperature, ZOZEN customized the combination of YQW series thermal oil heater + WNS series gas-fired 100kg steam boiler for railway system. Among them, YQW series thermal oil heater adopts forced circulation three-pass circular tube design for the sufficient heating surface. The energy-saving device added on the tail of the furnace body can greatly reduce heat loss, and the thermal efficiency is up to 95%. In addition, these two series of boilers are both equipped with advanced low NOx burner to realize the low emissions of NOx ≤ 30mg/Nm³; Moreover, the boilers are both adopt the packaged structure, after the boiler components are transported to the site, they can be put into operation once connecting to the electricity and gas, which greatly reduces the boiler installation cost.
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
