Vacuum Products vacuum boiler boiler is a hot water boiler, water heater, also called vacuum, vacuum boiler from the basic principles of the 1972 Zurich University of the invention. Vacuum boiler is mainly used for civilian heating, can be used in specific situations hotels, residential areas, commercial establishments like heating, sanitary hot water heating. Vacuum boiler vacuum boiler works a negative pressure vacuum is formed in a closed environment inside the furnace, the heat medium is filled in the body of water. Or otherwise heated by combustion heat medium water, heat medium water is heated to generate steam, the water heat exchanger heated by the pipe of the condensing heat exchanger, to achieve the supply of hot water. Vacuum boiler leak leak detection method described may be employed soapy water pressure. Wipe the first leak site (e.g., wire head, flange, etc.), and find a diameter 3-4mm thick sheet or plank is placed between the disk and the blade is about 80mm, prevent the boiler pressure proof sheet is bulged blade punctured. Allow operation of the burner, turn off the vacuum and high vacuum diaphragm valve means, so that the pot 0.05MPa pressure rise, closing the burner, pressure, liquid soap applied with a brush in the presence of all possible leak site, carefully, if leakage point will produce bubbles. Note that the pot pressure should not exceed 0.1MPa! For an examination site: explosion-proof valve, high vacuum diaphragm valve (hose connection), the furnace outfall seat, mirror, automatic vacuum device, a pressure control means on the furnace level, water temperature and other probe mounting interface. Found leakage diaphragm valve position required to open the high vacuum vapor discharge, reinstall the leak. After installation is complete again with soap and water leak detection method for detecting pressure, missing dots after confirmation, closing the diaphragm valve is opened after the high vacuum vapor release, and the plates come between the blade and the disk, closing the circulation pump, and then evacuated so half an hour to run the apparatus evacuated to a vacuum state.

Traditional boiler has its own Achilles' heel, decided that life is not long. Effect of boiler life to resolve the fatal weakness of traditional, dedicated 2019 vacuum hot water boilers supplier of the sealed boiler tank pump vacuum suction force, a vacuum state, not in contact with the air, never oxygen corrosion. Boiler water is heated by an external heat exchanger, furnace, smoke tube heat medium only in contact with water, the complete elimination of scale formation, to maintain efficient operation for many years; backwater circulation system and the boiler heat medium water do not mix, smoke stable, no condensed water, completely solve the condensation corrosion, significantly extending the life of the boiler. Vacuum hot water boiler whole life of more than 20 years.

2. boiler technology energy-saving measures (1) strengthen the technological transformation of inefficient boilers. Due to our limited economic base, not all older boilers have been updated. For updates not included in the scope, efficiency is not high but there are more defective boiler should strengthen technological innovation. Technological transformation of industrial boilers, should try to achieve a multi-effect of the change is necessary to improve the thermal efficiency to save fuel, but also to increase output, reduce pollution and achieve civilized production, but also to adapt to burning low quality coal. (2) boiler should make full use of frequency control technology. When selecting the boiler pump and fans, are considered certain margin in the rated load, so that in fact the boiler operation, the fan and the pump flow is less than the rated flow equipment, are required to be adjusted. Is adjusted by adjusting the throttle in the past, i.e., OFF or the throttle opening degree smaller Importers baffles, the flow rate is reduced, but not significantly reduced motor power. Frequency is reduced by the drive motor speed, the motor output power decreases. Frequency control for pumps and fans, general can save 30% to 40%, the investment can be recovered through two heating season, at the same time, due to the deceleration operation, reducing mechanical wear and extend bearing life, improved mechanical reliability sex. (3) the rational use of automatic control technology boiler. Boiler operation, automatic control can improve boiler efficiency, energy conservation. In recent years, automatic control technology and the rapid development of computer control, and more Sheung drum water level automatic control device, automatic control and computer control the combustion process in the oil and gas boilers more general application, for Stoker, some boiler monitoring the use of computer rooms, manual adjustment is also received good results. Boiler automatic control and computer monitoring instruments should be simple, practical principle. (4) promote the use of heat pipe heat exchanger. At present, the domestic part of the boiler flue gas temperature is too high, a large heat losses, reduces the thermal efficiency of the boiler. Can effectively heat pipe heat exchanger flue gas heat recovery boiler, the gas - liquid heat pipe heat exchanger is mounted in the boiler feedwater heating flue, significant energy saving effect, only one heating season investment can be recovered for a heat exchanger. (5) using the condensing heat recovery boiler technology. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated, it does not consider heat loss in a high latent heat of vaporization of the fuel heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and water vapor to enhance the thermal efficiency, the condensed water can be recycled. (6) reasonable steam accumulator. The steam accumulator is an energy save type apparatus, steam accumulator principle is that when the boiler load is reduced, the excess steam is fed into the boiler the steam accumulator and the steam under a pressure becomes high pressure saturated water. When the heat load increases, the amount of evaporation in short supply when the boiler, reducing the pressure accumulator, i.e., the high-pressure saturated water is separated into a low pressure saturated steam and water vapor produced by the user for use. Steam accumulator fuel savings typically 5% to 15%. (7) The vacuum deaerator technology. Vacuum deaerator oxygen is an energy save type method. Currently, oxygen supply and drainage method use large industrial boiler thermal oxygen atmosphere. This method of heating water to boiling temperature should at atmospheric pressure, oxygen in the water to drain away. Thermal oxygen atmosphere has two shortcomings. First, the atmospheric pressure boiling temperature, consumes a lot of steam, the boiler to reduce the effective use of heat. A 10t / h boiler feed water heated from 60 deg.] C to 105 ℃, steam consumption about 0.7t / h. Second, because the temperature of the boiler feed water economizer to improve the average water temperature increase, reduce heat economizer temperature, exhaust gas temperature increases, heat losses increase. These two points are the thermal efficiency decreases. And when the vacuum deaerator, the degree of vacuum is maintained at 7.999kPa (60mmHg), as long as the water temperature is heated to 60 deg.] C can achieve the purpose of oxygen. This not only saves steam and reduces exhaust losses, thereby improving the thermal efficiency of the boiler. (8) boiler water treatment technology to promote imports. It is estimated that imports of internal boiler every knot 1mm of scale, the overall thermal efficiency of a decline of 3%, and imports affect the safe operation of the boiler, through effective water treatment technology and cleaning technology, imports of non-boiler scale operation.
