which boiler info onbi boilers condenser
Commercial electric which boiler info onbi boilers condenser maintenance and meticulous care of the matter is what commercial electric boiler maintenance and meticulous care of what matters is: 1, the general commercial electric boiler 1--2 years to be sure of the commercial electric boiler maintenance, help commercial electric boiler in normal operation, regular maintenance for commercial electric boiler is the basic guarantee its normal operation. It shall be accompanied by safety regulations when boiler factory technical design documents, the real product quality certification, safety and use and maintenance instructions, supervision and inspection confirmed (Safety Supervision, Inspection and performance certificate). 2, boiler maintenance, must be cut off and must relief. Water level should always be kept clean, rinse purge valve is opened, the water level in order to ensure a clear day. Burner should be every two months removed from the boiler, carefully wipe out foreign materials such as coke and dust. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities, carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. Boiler installation, inspection maintenance, transformation. After construction, the construction unit of Special Equipment To Quality and Technical Supervision, Inspection and declared the boiler installation supervisory inspection and hydrostatic testing. After passing by the Quality and Technical Supervision, Special Equipment Inspection, County of Quality and Technical Supervision acceptance to participate in group 4, pulling the safety valve once a day, to prevent rusting failure. After the work is completed, check whether the tools, materials, complete accessories, such as to prevent left in the furnace space inside. Someone delisted from the job site only after acceptance, good maintenance records, to prepare for subsequent queries.
"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small which boiler info onbi boilers condensers county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.
In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.
Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.
After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "
This year the city built-up area of the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.
City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
The temperature difference between the upper and lower walls of gas-fired which boiler info onbi boilers condenser will cause certain damage to the boiler body, which will cause the compression stress on the upper wall of the boiler and the tensile stress on the lower wall. When the stress reaches a certain extent, the gas-fired boiler can be damaged or even cracked. Why would there be a difference in temperature? That is because there will be a certain degree of difference in temperature between the upper and lower walls of the drum in the initial stage of ignition of the gas-fired boiler, which is due to the low temperature of the metal steam on the wall of the boiler at the initial stage of heating up, and the condensation and heat release of the steam on the wall of the drum. The contact heat between the lower wall of the drum and the water also occurs, but the exothermic coefficient of steam condensation is higher than that of water. Larger, more heat absorption on the upper wall of the drum, so the upper arm temperature of the gas-fired boiler is much faster than the lower wall. This requires us to pay attention to some operation items in the operation of gas-fired boiler, so as to avoid the damage of gas-fired boiler and ensure the normal operation of gas-fired boiler.
Gas is closely related to the transformation of coal-fired which boiler info onbi boilers condensers Food Factory 10t program Note Food Factory 10t coal-fired boiler gas-fired boiler plant food program Note 10t coal-fired boiler gas boiler burners Notes program selection and arrangement of the furnace, so flame furnace should be sufficiently filled, not dead air formed near the burner flame to avoid mutual interference, when a low load flame will remain in the center position of the furnace body. Avoid flame center offset from the center of the furnace; unburnt gas and air mixture is not contacting the heated surface to prevent incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, surface strength in order to avoid excessive heating leading to overheating of the tube wall. Considering the gas burner arrangement and air tubes rational arrangement, operation, maintenance, and easy maintenance. 1) Gas boiler furnace exit gas temperature from the high temperature corrosion and fouling control, is allowed to be about 1300 ℃ or higher range. After the coal-fired boiler gas boiler, since the heating surface and the much less significant fouling, heat transfer environment is further improved, the heat loss can be obtained is not completely well controlled, the boiler efficiency can be increased 5 to 10%. 2) using micro-pressure boiler furnace combustion. We should strengthen the boiler furnace wall, sealing performance right.
