automatic gas fired vacuum boiler

Vacuum gas automatic fired vacuum boiler introduce vacuum gas boiler Product Description: Vacuum gas boiler is the use of water at different pressures, the boiling temperature characteristics vary to carry out the work. At one atmosphere, the boiling temperature of water is 100 deg.] C, and under a pressure of 6mmHg, the boiling temperature of water was 4 ℃. Vacuum hot water unit is operating in the pressure range 200mmHg ~ 500mmHg, the corresponding water temperature was 66 ~ 88 ℃, hot water under pressure in the vacuum of the work unit, the combustion temperature of the heat medium water temperature rises to saturation, and generating steam in the water of the same temperature. At this time, through the heat exchange (heating or hot water) inside the water, the cold water in the steam tube outer tube is heated in hot water, and passed to the user, and the water steam outside the pipe were cooled and condensed back to water is heated water drops , thereby completing the cycle. The main features; vacuum hot water units always run under negative pressure, never inflated the risk of explosion, with safety and reliability atmospheric pressure boiler has unmatched; built-in stainless steel heat exchanger, heat transfer efficiency, water quality cleaning; built rope stream smoke tube sheet, increasing the effect of heat transfer, so that a more compact structure; imported burner, combustion efficiency, noise, low emissions, to achieve the requirements for a class Country; integral with a square configuration, overall spraying, shape compact appearance. Smoke tube equipped with a helical spoiler, heat strengthen, improve boiler efficiency and reduce operating costs. Indirect heating: main body of negative pressure, the system pressure; large furnace technology: effective to increase the area of ​​heat radiation unit, reducing the NOX emissions; high water boiler water, inside the body to ensure that never scaling, corrosion. Boiler and heat exchanger integrated design, saves space and greatly reduce floor space. Shell type using three return all wet back structure, dynamic heating, heat sufficiently. Low temperature boiler operation under negative pressure, safe and reliable. Automatic control system, no special duty. Imported burner, combustion efficiency, noise, emissions low. Unique pulse level detection circuit structure, reliable performance. Inlet / outlet water temperature display makes it easier to grasp the boiler operating conditions and systems. High centrifugal glass wool insulation using multi-layer, heat loss. Protection: 1, the boiler has a voltage high, ultra-low protection, when the supply voltage exceeds the normal range, the alarm and automatically cut off the power boiler. 2, the boiler has a temperature sensor fault protection, each boot, the boiler control system first detection sensor condition, such as abnormal boiler is automatically cut off power and alarm. 3, the boiler having a water alarm function: When the boiler water level is below the safety level pot, the boiler automatically cut off power and alarm. 4, the burner flame failure alarm 5, overpressure sound and light alarm 6. boiler burner motor overload, fault protection 7. Automatic shutdown protection, as follows: a) a burner failure automatic shutdown, manual reset b) very low gas pressure automatic shutdown, manual reset c) automatic overpressure boiler shutdown, manual reset power d) of the safety interlock device interrupt automatic shutdown, manual reset heating gas boiler

The partnership, fast automatic fired vacuum boiler for the user responsible attitude to have left a deep impression on our fireman boiler operation is not very skilled, fast deliberately sent a party of professional and technical personnel for our on-site supervision of installation, commissioning and training to ensure that the latter can operate our good boiler fireman. --customer feedback

Vacuum, pressure, pressure hot water automatic fired vacuum boiler big contrast: now on the market boilers, boiler diverse species, into the advanced technology to promote the rapid development of the boiler industry. Hot water boiler to provide heat support a large number of all walks of life and living, is one of the important equipment indispensable. According to different boiler under pressure can be divided into the hot water boiler pressure, vacuum pressure hot water boiler and hot water boiler.

Learn vacuum hot water automatic fired vacuum boiler vacuum hot water boiler is a safe and reliable boiler varieties, developed since 1975, gradually became popular worldwide. Also for his safe and reliable operation, long life, adaptability, and efficient energy-saving features, the annual market share has gradually increased. Vacuum hot water boiler furnace divided into two parts; the upper half portion of a vacuum chamber (vacuum vapor chamber), which is provided with a tubular interior space of the vapor - water heat exchanger for heating circulating water flowing through the heat exchanger . The operating principle: vacuum hot water boiler is running, the negative pressure in the vacuum furnace body heat medium water absorbs heat energy released by burning fuel, Boiling water circulating system encounters a stainless steel heat exchanger of the low temperature steam, low temperature steam rises, heating recycled water to users for heating or hot water. Itself is cooled steam condenses into water droplets fall to the surface again after the heating medium is heated, thereby completing the entire cycle. Heating medium water constantly in the body with a closed circulation heating evaporation == == == heat medium condensed water, condensed water without added thus, no danger of burning air. Vacuum hot water boiler using soda condensation heat, all heat exchangers operating condition, soda condensation heat transfer coefficient is the highest.
