combined 0 5 ton vacuum hot water boiler supplier

Vacuum hot water boiler in use, what convenient place? Vacuum hot water boiler is mainly used in shopping malls, hotels, schools, residential housing, entertainment venues and other officers to concentrate on providing sanitary hot water and heating. A negative pressure inside the boiler, and the outside atmospheric pressure is low, compared with the conventional heating device, having high safety, no explosion, expansion cracking and other dangerous situations. So, good quality combined 0 5 ton vacuum hot water boiler supplier which has the advantage of using it?

Comparison of heat efficiency comparison of two boiler vacuum boiler pressure boiler: 1, the vacuum boiler water volume is small, a water do not participate in the systemic circulation, the burner startup operation more often than atmospheric boilers, burner thermal efficiency is low, the degree of vacuum under the premise of stable, high-energy vacuum boiler thermal efficiency of 91%, the degree of vacuum devices to change operating subsidiary boilers instability will reduce the thermal efficiency. Operating costs can not be stabilized, as the vacuum pumping equipment and reducing the useful life of the control element, to increase the thermal efficiency of the failure rate will be lower. 2, boiler pressure hot water boiler volume greater than the vacuum, nor participate in a water circulation system, less the number of starts burner, burner high thermal efficiency, thermal efficiency of hot water boilers is 91%, and stable efficiency boiler and hot-water operation, no then the impact of multi-device failure rate, the structure is simple and durable. Comparison of the heat exchanger structure is built of a vacuum through a steam boiler heat exchanger, a short warm-up time. U-carrying stainless steel boiler tube heat exchanger, a cleaning may be opened flange, the other end can not be opened can not be completely cleaned thoroughly heat exchanger. 2, the boiler through the water pressure - heat exchange, the preheating time longer than the vacuum boiler water. Built using copper-line boiler tube heat exchanger, there are two flanges, more thorough cleaning. Compare the life of a boiler, the boiler due to the vacuum suction vacuum boiler work, less time to add water to reduce boiler fouling, corrosion and other problems oxygen, due to the boiler closed, water can not once a year dosing maintenance, boiler pressure has also taken advanced international scale, anti-corrosion measures oxygen, the actual life of the boiler and pressure boiler considerable, even if the long life of the body a little, boiler control elements, the service life of the burner can not be too high pressure boilers. 2, boiler pressure hot water boiler with a water softener equipment boiler fouling problems can be overcome, itself an indirect hot water boiler feed water is also very small, sacrificial anodes to reduce the oxygen corrosion protection internationally, annual boiler maintenance dosing may slow down steel oxygen corrosion, boiler plate and the outer heat insulation take a unique two-component embodiment, with water, acid and alkali resistance, oil and other functions, since the insulation adhesive material applied on the boiler body, with the boiler plate to prevent oxygen corrosion in air, vacuum boiler glass wool insulation, can not prevent oxygen corrosion of the steel sheet with air, so the life of the boiler water is not lower than the vacuum boiler 2 times higher, and the life of no basis.

Traditional industrial boilers difference is that the internal pressure of the vacuum boiler is less than the ambient pressure (vacuum food you can think of), mainly used for hot water output. This is because in the case of reduced pressure, the boiling point of water is also reduced, so that at low temperatures can be done quickly boil.

Recently, located in Yan'an City, Shaanxi Province, Huanglong held removal of coal-fired boilers mobilization meeting, and promote the coal-fired boiler, "clear" work, Huanglong improve the overall air quality of the environment. The meeting was chaired by the Deputy Mayor Cao Zengjun, County Authority, Environmental Protection Agency, the Public Security Bureau and other coal-fired boilers Chaigai leading group members of the unit involved in coal-fired boilers and Chaigai of 16 enterprises and units attended the meeting.

At the meeting, urban management bureau announced the "urban transformation of coal-fired boiler demolition plan", and county coal-fired boiler demolition work arrangements for the deployment. Program pointed out, the county government before the end of June to remove their coal-fired boiler steam tons per 20,000 yuan subsidy standards in accordance with the relevant provisions of the provincial coal-fired boilers Chaigai subsidies, Chaigai completed in the first six months to the end of August unit task of tons of steam per 10,000 yuan subsidy standards, after the completion of the end of August Chaigai units should be punished to the unit in addition to the removal of subsidies, the person in charge accountable.

A coal-fired boiler Chaigai work is the key point to win the Battle of the blue sky, Huanglong is an important measure to improve the quality of atmospheric environment, the relevant units should fully understand the importance and urgency of the boiler Chaigai work, according to "own boiler demolition themselves, change themselves, government agencies take the lead in demolition, lead change, limited time limit must be removed, must be changed "requirements, implement them.

Second, the change involved units to firmly establish the overall awareness, to overcome the luck, to seize the opportunity boiler Chaigai premium policy, a reasonable choice of the transformation of the way, adhering to standards, early arrangement, early deployment, early start.

Third, the government supervises the room should work together with urban management, environmental protection and other departments, inspectors conduct regular supervision, to dismantle ineffective, slow-moving unit, to be criticized, and timely feedback evaluation to do, do you want to do a good evaluation appraisal work; County JISC to errant Chaigai, affected units and individuals county atmospheric objective assessment of the results, in accordance with the "air pollution prevention of accountability measures" be accountable, accountability, ensure on schedule to complete the work Chaigai city coal-fired boilers.
