Several causes of water pressure in the vacuum vacuum boiler for hot water system 1100kw efficiency indicators are carrying substantially all parts of the coal gas impressive action, application of vacuum hot water boiler, to reduce the very high infected fine particles, while the nitrogen oxides and other toxic gases, emissions have also been suppressed. Efficiency is a key indicator of a measure of navigation vacuum hot water boiler, look under vacuum pressure hot water boiler efficiency indicators together after several incentives continued. After inquire stakeholders, vacuum hot water boiler heat losses probably exists in two portions comprising: air-fuel combustion flue gas emissions ignore want heat loss. Emission reduction of heat loss can be fitted in vacuo latent heat of the flue hot water boiler recirculation configuration, application or system will be more advanced condensing boiler. Combustion air-fuel ratio over the substandard Analysis: Usually ejector vacuum hot water boiler burner, causing the air-fuel ratio can not be flexibly adjusted. Very many vacuum hot water boiler uses a mechanical blower burner, causing air-fuel ratio over the causes are the following: over the air-fuel ratio can be roughly divided into two types comprise situations: when oxygen is in excess, there will be Unlimited air is excessively low thermal conductivity, resulting in improved vacuum hot water boiler operating costs, low efficiency indicators vacuum hot water boiler; when oxygen is insufficient, there will not fully kindled state, a low vacuum hot water boiler efficiency index.
The difference between the atmospheric pressure hot water vacuum boiler for hot water system 1100kws, hot water boilers vacuum? Currently, many have adopted residential district heating boilers, hot water boiler performance and therefore plays an increasingly important role in the heating of the residents. The most common on the market are vacuum hot water boiler and boiler pressure hot water boiler. However, many consumers know these two hot water boilers thorough enough, there may be some bias. A, different security present, primarily professional vacuum hot water boiler hot water boiler, a hot water boiler internal negative pressure can achieve the purpose of rapid combustion temperature, while by changing the configuration of a vacuum hot water boiler may be related to atmospheric hot water boiler. Therefore, security is more obvious. However, when using hot water boiler pressure hot water boiler as long as the use of some type of guarantee ventilation, and therefore pressure hot water boiler is particularly safe and reliable. Second, due to the small amount of water heating efficiency of different vacuum hot water boiler, a water requires multiple cycles fewer burner heated hot water boiler and the atmosphere of a large container only opened once the burner can achieve a good heating effect can be efficient heating. Hot water boiler circulating water and atmospheric pressure hot water boiler. Thermal efficiency of the furnace is higher than the thermal efficiency of the vacuum hot water boiler. Third, the complexity of the equipment in order to ensure different vacuum, vacuum hot water boiler must be installed infrastructure series a vacuum pump, but the average hot water boiler pressure control device need not be employed to maintain the vacuum. Therefore, no complicated control equipment required personnel to operate more simple, the complexity of the boiler equipment in use also have greater advantages, meet the needs of more consumers.
Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station steam vacuum boiler for hot water system 1100kws. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).
The principle of a vacuum hot water vacuum boiler for hot water system 1100kw, hot water boiler works vacuum: a vacuum hot water boiler had already appeared in the early 1970s, first in the finished product is available in Japan. Development of domestic hot water boiler in a vacuum there are some manufacturers in the late 1980s, but due to technical issues, has not been promoted. Now that Japan has more mature models in China has also been a joint venture factory, the author is the choice of a dual-loop vacuum hot water boiler of the plant. The structure of vacuum hot water boiler, by the combustion chamber (furnace), water, vacuum vapor chamber, heat exchanger, heat medium consisting of water or the like. Vacuum state within the body, from the outside air, a sealed state is formed. HTM furnace and covered with water in a sealed tube and within the body, by the pressure of the negative pressure in the steam chamber is maintained below atmospheric pressure, when the heat medium water confined in the inner combustion heating, boiling up immediately, generating heat medium water steam of the same temperature. Steam generated in the machine during the ascent, the contact surface of the heat exchanger is disposed in the negative pressure of the steam chamber, since the water temperature in the heat exchanger is lower than the steam temperature, steam condenses on the heat exchanger surface and release a large heat of vaporization , the water heating heat exchanger, the condensed water under the action of the policy back to the heat medium water again. Accordingly, the heat medium water is constantly "boiling evaporated = = = heat medium condensed water" in a closed loop body. No need to supplement the condensed water, no air burning danger. Water heat exchanger is supplied to the user for heated sanitary hot water and air conditioning. To ensure the reliability of the vacuum hot water boiler operation, the three manufacturers to ensure: 1. In order to ensure a degree of vacuum inside the boiler, at the factory to create a rigorous inspection, the quasi gas leak detection, to ensure that the production process boiler airtight tank. To maintain the degree of vacuum, and to prevent the event, the plant is equipped with a standard suction pump. When the vacuum tank hot water boiler body, the heat medium water is heated to 90 ℃, according to the degree of vacuum exhaust pump automatic operation of the tank, not only the air out of the tank, also the presence of dissolved oxygen in water to remove the heat medium, to keep certain negative pressure, produced inside the tank will not corrode. 2. The heating medium water through a special manufacturing plant impurity, oxygen, water softening treatment, in the production of disposable infusion, can be recycled at runtime, without generally no special filling. I visited the plant in the design of the user survey, a Shanghai Electrical Machinery Plant, 87 years put into operation a vacuum hot water boiler, use a decade overheated media never raise water, which can still work normally. 3. The heat exchanger of the boiler with special requirements, using SUS444 stainless steel tube, which requires a special process during tube processing. 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.
