Select heating central heating boiler suppliers what are the considerations for the heating system, we propose the functional principle of the boiler and a lot of doubt, this simple to explain: household independent heating system, the first essential is a stable heat source, that is, heating boilers for the family is a simple heating boilers, for it is a city or a region, we need a lot of heating boiler heating stations were running protection of the public. 1. The inner two energy saving boiler combustion process, combustion of a fuel itself, and the other is to produce the fuel gas flammable mixture in a sealed high-temperature gasification and combustion processes. Boiler reasonable structure, the fuel gasification process stability, integrity, and the use of anti gasification burner, arranged dedicated economizer. Up to 85% thermal efficiency of the boiler, energy-saving effect. 2. The water temperature and water flow constant water temperature, no, no, no change, is a measure of the boiler is the main quality standards. Old residential water heaters commonly large amount of water or less, high or low temperature. According to a company's HVAC engineer, boiler now only one instead of the old heat exchanger, gas and water flow ratio control is not an exact match. But today's new boiler using a secondary heat exchanger. By completely secondary heat exchanger, complete remission contradiction gas two-phase flow of water, the water temperature is fairly constant, the flow does not change. 3. easy to control a good control system is an effective guarantee the normal operation of the combustion safety, testing, maintenance, daily operation and failure analysis are all important. Therefore, the choice of high-performance boiler is particularly important, especially for the elderly and children in the home. By-room temperature control not only the freedom to set their own needs heating temperature, can also be pre-set temperature before returning home, so that they will be able to enjoy the warmth of a home. 4. Look for boiler service procurement business, buying boiler products, especially large tonnage, is perfect after-sales service is an extremely important factor. In fact, due to the imperfections of production and after-sales service network, many boiler brands in the market is difficult to guarantee. Business and professional services to improve network and service system, not only the performance of enterprises and planning, more attention is to look at business and professional ability, each link is a professional, to ensure efficient and smooth transition of the whole process.
On what scale will be hot water central heating boiler supplier hot water boiler scale in general, these are the following: 1 carbonate scale: Its main component is calcium and magnesium carbonate, but is mainly calcium carbonate, which is generally white color, which produces parts, mainly in some relatively low temperature site. 2. sulfate scale: its main component is calcium sulfate, is relatively hard and dense, white or yellow color, which appears parts, mainly elevated temperature strength and evaporated in a relatively large evaporation surface. 3. silicate scale: its composition is more complex, silica and the like, which is very hard texture, off-white color is mainly present in the boiler heating surface strongest parts. 4. Mix scale: scale and mixtures of these types is the rust, which has a plurality of colors, and a multi-layered form, which is not fixed portion occurs.
It can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation in process design, which has the advantages of rapid cooling and heat transfer capability and smaller temperature difference between heat transfer and heat transfer, which can increase the application range of heat transfer unit equipment and the design scope of heat transfer operation. It also provides possibility for some previous designs which are limited by heat transfer rate or temperature difference, such as recovery of heat energy by small temperature difference, small temperature difference cooling, rapid and accurate constant temperature control and so on. This is due to the fact that plate heat exchangers are also thin-layer heat exchangers. The thermal deviation of each parallel heat pipe group should be reduced as far as possible, for which the return water of the system entering the central heating boiler supplier should be adjusted and distributed. For ordinary low-temperature hot water boilers, the hot water flow rate is large, can The natural distribution, that is, the amount of water entering each parallel pipe group, is allocated naturally according to the heat condition of each pipe group and the size of pipe resistance. Although the structure of natural distribution is simple, but the safety and reliability of boiler operation is poor, for high temperature hot water boiler, the relative water quantity is less, so it is not suitable to adopt natural distribution mode, but the valve should be used to adjust the distribution, according to the size of heat load of heating pipe group, Supply the corresponding circulating water to ensure that the outlet water temperature of each parallel loop does not vary greatly. At this point, the outlet water temperature deviation of each loop can be controlled within 10 degrees Celsius. The heat pipe of the retrofitted hot water boiler must be kept to a certain extent. Water flow rate to ensure heat pipe cooling, prevent oxygen corrosion and the deposition of impurities in the water. The downlink heat pipe should also maintain sufficient water speed. After modification, the stagnant zone of water in the boiler should be reduced as far as possible, especially at the end of the drum. Otherwise, oxygen corrosion can be easily caused. In order to remove the gas from the water in time, the exhaust valve should be set at the highest point of each loop of the boiler. When refitted into forced circulation hot water boiler, measures should be provided to prevent sudden power outage and kettle vaporization when pump is stopped.
