combined vacuum boiler supplier in africa

Vacuum hot water combined vacuum boiler supplier in africa on those points we need to know: we usually refer to the hot water boiler is divided according to different ways, have different classification; wherein if in accordance with the boiler pressure points, then, can be divided into atmospheric hot water boilers, pressure hot water boiler, vacuum hot water boiler; for atmospheric pressure and we may be more understanding, that comparison, for vacuum boiler maybe not so familiar with, then, as far as it relates to the problem, we have to carry out simple doubts, let us better understand its characteristics, uses, etc. 1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum two kinds. Physical vapor space means no presence of particles, industrial vacuum pressure refers smaller than a standard atmospheric gas space, refers to the state of the lean gas, usually obtained with a special vacuum pumping machine, the vacuum in the vacuum are industrial boiler vacuum. 2. What is a vacuum hot water boiler? The so-called vacuum boiler, also known as vacuum phase transition boiler. When the normal operation means, the boiler pressure below atmospheric pressure inside the medium, the cold water is heated by the boiler phase change heat mode. 3. What are the key technology of vacuum boiler is? Key technology is the degree of vacuum vacuum boiler to maintain long-term stability, leakage rate is minimal. 4. What is the vacuum hot water boiler heat exchanger the material is? Heat exchanger disposed in the vacuum boiler SUS304 stainless steel tube. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate. The vacuum hot water boiler temperature control temperature control two ways:? Media outlet water temperature control and temperature control. The default for the water temperature control medium. When the water temperature is selected to control the combustion temperature is automatically adjusted with the water, but if the water medium temperature exceeds set limit on the medium water, burner heating was stopped, the water continues to be lower than the medium by the burner outlet temperature regulator when a temperature of 5 degrees limit status. 6. A vacuum boiler safety device which has a safety device for a vacuum boiler:? ① heat medium water temperature control, may control the temperature inside the furnace heat medium water; ② the heat medium water level control, may control the heat medium inside of the furnace body the level of water; ③ the beginning of the pressure, when the abnormal pressure rise within the furnace operation, the combustion is automatically stopped; ④ hot water temperature control, when the over-temperature water temperature, the combustion is automatically stopped; ⑤ destructive protection: explosion-proof valve. When abnormally high pressure furnace, steam furnace body is released to the atmosphere, to ensure that the unit never danger of explosion. 7. What are the main features ① vacuum boiler pressure vessel does not require local authorities to monitor, installation needed to use;? ② do not need to pay, no good water resistance, long life; ③ low energy efficient, operation and management costs; ④ reduce auxiliary, saving investment; ⑤ high safety performance. 8. Why ① vacuum boiler can be small energy radiative heat loss, the furnace is sealed vacuum vessel, itself has good thermal insulation properties; ② high heat exchange efficiency, the furnace body steam - water heat exchanger thermal efficiency is water - water? 10 times the thermal efficiency of the heat exchanger; ③ small thermal inertia: small boiler size, low water heat medium, the heat capacity is small, small thermal inertia and therefore, the reaction is sensitive to load variation. The boiler is turned on, i.e., 5 to 8 minutes with a hot water. ④ heating surface does not scale, energy saving. 9. Why vacuum hot water boiler blast furnace will never work in a vacuum, not a pressure vessel;? Body sealing of certain heat medium water, air will not burn in any state; the body with multiple self-protection device (anti-overheating, freezing, water shortage bit too high anti-pressure, shock, anti-gas fuel supply enough water, etc.). ? 10, vacuum boiler boiler host large investment it though the price is higher than ordinary vacuum hot water boiler, but it can save a lot by vacuum boiler auxiliary equipment investment: plate heat exchanger, a circulating pump, expansion tank soft water treatment equipment and so on, can also be save the corresponding pipeline installation fees, accommodation fees auxiliary power system control fees, investment is still lower than the average integrated hot water boiler system.

1. Complete gas combined vacuum boiler supplier in africa heating energy efficient gas boiler heating power key to progress, energy savings should follow the completion of the following two criteria. First, advances in gas boiler power. Here said boiler power refers to the power of this season boiler boiler group or groups. Power gas-fired boiler primary season progress through two ways to complete. First, during the heating, the boiler will try to start and stop times, idle time reduction. Thus these operations will form part of a certain level of gas and heat consumption. Second, the appropriate share of the air conditioning hybrid and natural gas can be burned together with the power of progress, reducing natural gas consumption. Second, advances in power delivery network. In the pipeline transit, insulation, leak, hydraulic imbalance resulting in heat loss is the primary factor affecting the delivery of power. In the heat loss, the heating system, the vertical offset, the horizontal offset energy external network formed by the loss of most severe. Thus, to complete the power-saving, it is necessary to start from the presence of these disorders conditions.

2. The gas condensing boiler heating energy-saving skills 1. Skills condensate skills is the primary means of useful skills to complete the power-saving gas-fired boiler. Element in the presence of hydrogen rich natural gas, the natural gas during incineration may generate a lot of water vapor. In the exhaust process, the temperature rises, the water vapor is condensed can not be completed, a lot of thermal energy is wasted. Together with the high temperature flue gas discharged in the process will take many tropical significant, sensible heat and latent heat released into the atmosphere, present in the flue gas nitrogen oxide and other substances to form a certain level of air pollution, air quality impact. Primary condensing gas boiler through the use of condensing heat exchanger from the boiler exhaust gas present in the condensed water vapor, to complete the advancement of the thermal power boiler, and can effectively reduce air pollution. In other countries, the use of condensing skills now in sophisticated stage. With the development of energy-saving and environmental protection requirements, condensing skills in our use and also have to carry out more and more prospects. In the course of condensation skills, detailed device often used to recover flue gas condensation heat and the like. 2. The heat pipe heat pipe is a highly effective skills transfer element, which is one of the most important skills in space science and technology of high-tech components. A vacuum condition inside the heat pipe, the presence of appropriate amount of liquid having a thermal conductivity in this vacuum condition inside. When the heated liquid heat pipe heat must have been terminated, the inside of the heat transfer liquid is absorbed immediately, so that a sharp rise in temperature itself, until steam is generated. When the vapor rises to the other end of the heat pipe, i.e., when the cold end, the corresponding latent heat of vaporization released out of body heat pass. In this case the effect of the steam is condensed again into liquid is liquefied, by virtue of its own gravitational force back to the heated end of the heat pipe. The heat pipe is performed through the above-described repetitive transpiration, condensation cycle to complete phase transformation latent heat of the flue gas absorption, release, and thus useful for conducting heat is completed. Heat pipe air preheater can be useful for all heating air burning, smoke decreased during the onset of heat loss, strengthen the power boiler burning hot air, effectively improve the industry used to carry out. Air heat pipe heat exchanger may be useful to complete the via flue gas heat for preheating the air, and efficient for the boiler furnace to complete the hot air supply feed. Heat pipe skills of scientific, rational use not only bring huge economic benefits to the industry to carry out and complete the decline may be useful energy, reduce pollution, play an important effect in carrying out environmental protection and national economy.

3. The system of circulating water pump system circulating pump frequency inverter skills are important skills in accordance with a detailed user heat demand, the frequency of the circulating pump motor for speed, after the completion of the circulating water system useful for conditioning. Practical use of that reduced power loss may be useful in the process of distribution pumps, power saving is to save skills. Based on hydrodynamics know, the circulating pump, the circulating water which, as a link between the two pump speed pump speed; the head, between the two pump speed was proportional to the square contact; the shaft power, the pump speed between the two was is proportional to the cube of contact. Thus, using a pump frequency of skills in the gas boiler, you can cycle through the method of slowing the pump speed to complete the pump power consumption is reduced.
