natural gas vacuum water tube boiler for sale

Vacuum hot water boiler small science in recent years, a type known as vacuum hot water boiler boiler in the market caused no small wave, then vacuum hot water boiler is what kind of boiler it, to the side of a small fast Come prepared for your eleven. The basic principle of vacuum hot water boiler was born in 1972, University of Zurich, by forming a negative pressure in the vacuum furnace body closed, the heat medium is filled in advance in the body of water, heating medium water heated by combustion or other means, the heat medium water by vaporization and liquefaction of absorbing and releasing heat to the heat pipe heat exchanger, to achieve the supply of hot water. Oil, natural gas, gas, electricity -> combustion (heat conversion) -> heating medium water -> steam condensing heat exchanger after boiling -> exchanger -> Heat Conduction -> water, "vacuum" refers to an automatic vacuum apparatus and the pressure inside the boiler is lower than the outside atmospheric pressure is low with water a low boiling point characteristic, rapid heating of the heat medium water, increase the heat transfer rate. Since the boiler internal pressure is lower than the outside world, it does not appear the boiler exploded, burning deformation and other adverse conditions. Fast Multi Party conventional vacuum boiler type, as fully condensed in vacuo premix hot water boiler, low nitrogen vacuum hot water boiler is coupled, solve the needs of different users in different sectors. By using advanced FGR, such as premix low NOx combustion technology, ultra-low nitrogen oxide emissions, environmental protection is very friendly. While adding condensing technology, making the boiler operating efficiency upgrade more than 10%, significant cost savings for businesses.

Comparison of boiler failure rate and safety between boiler failure rate: 1, degree of vacuum in the vacuum boiler furnace boiler * important indicator of stable stable operation of the four main factors often influence the degree of vacuum: 1) boiler and valves, The instrument has no leak points, including the inlet valve and instrument currently can not guarantee no leakage occurs within 3 years. 2) whether the control section failure, the boiler controller and negative pressure controller also fails in operation is inevitable, such as the failure rate even higher internal controller 3) a vacuum pump, if the three-way electromagnetic valve normal, due to the vacuum pump, three-way solenoid valve is not run frequently, imported and seizure operation also prone to failure. 4) Load not have mutations, altered boiler load is normal to the boiler, the boiler can meet generally 30% -100% of the load adjustment. Above failure will cause the boiler to change the degree of vacuum, should check the airtightness of the boiler, the control section is normal, the vacuum pump, the three-way solenoid valve is normal, check load changes, if the check is normal and negative pressure controller setting, after everything is normal vacuum level recovery boiler can also normal use, or to repair a comprehensive inspection shutdown. The actual operation of the vacuum boiler breakdown maintenance rate is higher than the pressurized steam boiler, a steam boiler control requirements than. 2, pressure boilers including a boiler only basic time, temperature, level control, controller selects imported hot water boiler, as compared to a lower failure rate. No need to maintain the degree of vacuum control equipment, no complicated control equipment, personnel operating requirements simpler than vacuum boiler, the less chance down for maintenance, the actual running hot water boiler to be much more stable. Compare the safety of boiler: 1, vacuum boiler if for the above four factors the degree of vacuum boiler is not guaranteed, it may cause a rapid rise in boiler pressure, boiler is a closed structure, if careless operator, it is possible to be there dangerous pressure steam boiler, vacuum boilers run more negative safety is based on the premise degree of vacuum boiler must not be problems. 2, atmospheric pressure hot water boiler boiler-through the atmosphere, as simple as boiling water, any failure will not cause pressurized boiler, boiler more secure, truly without any danger.

November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast boiler - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.

Large-scale thermal and thermal power plants can be built in industrial concentrated areas, large and medium-sized cities with large heating loads can be built in northern large and medium-sized cities, operating according to cogeneration of heat and power in heating season and condensing steam mode in non-heating season. In the case of condensing units, heat supply can be achieved by means of low vacuum operation of condenser or drilling and pumping steam in the connecting tube of high and low pressure cylinder of steam turbine, and remarkable energy-saving effect can be obtained.
