How to select condensing heating hot water boiler for sale condensing hot water boiler how to choose? Recently, with the improvement of people's awareness and promotion of low-carbon living national energy saving publicity, condensing hot water boiler increasingly popular in our country. In the face of the market claiming they are a larger number of condensed water boiler manufacturer and the price gap situation, difficult for consumers to determine how to choose a condensing hot water boiler, told us the following selection techniques condensing hot water boiler. Let us first find out what kind of boiler is condensing boiler, and their performance advantages are: this boiler on the basis of the original boiler can be increased by 3-6% efficient, but its comprehensive energy-saving effect is not obvious, mainly because of the way combustion size fire switch. Quasi reason condensing boiler combustion temperature nitrogen oxide emissions are greater than 120mg / m3. But the biggest advantage of this boiler is cheap. Fully premixed condensing boiler, or many professionals say, it is the real concentration. Since the boiler was designed with a deep full-condensation techniques, thermal efficiency as high as 109.1. In addition, all-frequency premixed combustion technology, the boiler 40% energy saving than conventional gas boiler, energy-saving effect is very obvious. As the cost of the boiler, boiler prices much higher than the prices to be condensing boilers, recovery of investment costs over one year takes about a year. The national coal industry in recent years due in large part to change the gas over the past two years, large and small gas boiler manufacturers, has been in short supply situation. At the same time, there have been some speculators, they want to take this opportunity to get back some money. Condensing gas hot water boiler is an energy-saving, environmental protection, safety, technical and service demanding products. Each manufacturer may feel that the Internet is good, but if you go to the manufacturers site visits, you will find a big gap, so it is necessary to go to the manufacturers site visits!
Factors that affect factors superheated steam temperature changes affect food factory superheated steam boiler plant food temperature variation effects superheated steam boiler temperature variation food factory, 1, 2 changes, and the air volume ratio of 3 changes, burner fuel properties and 4, 6, 7, change the saturated steam temperature change and desuperheating water flow operation mode change in water temperature in the pulverizing system 5, the heating surface cleanliness variation boiler load variations. Change in fuel volatile carbon content, calorific value and the like: 1. Variations in the nature of the fuel. When the roughening coal, fuel combustion in the furnace a long time, the center of the flame increases, the steam temperature. When the fuel water is increased, the heat absorption of water evaporation furnace, the furnace temperature is lowered, the increase in humidity, but also increases the volume of the flue gas, the flue gas flow increases, reducing the superheater heat radiation, convection superheater heat absorption is increased. 2. And change the air volume ratio: when increasing the oxygen content of the furnace, the low temperature due to heat absorption of cold air, the furnace temperature is lowered, the furnace outlet temperature. At a total gas flow is constant, a change will also cause shifts air distribution steam temperature. When a low flow rate is insufficient, part of incomplete combustion of pulverized coal, the flame center is moved upward, the furnace exit gas temperature. 3, changing the operating mode of the burners and pulverizing system: operating system will result in an upper pulverizing the steam temperature is increased, the swing angle of the burner changes, the change in center of the flame, steam temperature changes.
Buy domestic boilers domestic boilers method is mainly used for heating or hot water when used in life, the use of safe and efficient equipment, widely used, then the purchase should pay attention to those problems? Many people may not know much about this small series for everyone to explain the specific purchase method. First, the good general boiler water temperature constant, constant water flow, the use of secondary heat exchanger, gas and water with ease conflicts, the water temperature constant. Second, energy-efficient and comfortable. Whatever your choice of products, energy efficiency and comfort is to improve the basic quality of life standards. Electric heating is a few years ago once popular heating methods, but because power consumption is too large, may also increase security risks, therefore, energy-saving and comfortable heating equipment has become a consumer demand. Plumbing boiler mostly used wall-mounted gas boiler, external to the indoor thermostat, in order to personalize the temperature regulation and energy saving purposes. Indoor temperature controller efficiency of 20 to 28% of the gas cost. Third, easy to control. A good control system is normal household boilers, combustion operation to ensure the safety of inspection, maintenance, daily operation and fault analysis has important significance. It is essential to choose a high-performance boilers, especially at home with the elderly and children, not only to control the temperature of rooms according to their needs free to set the heating temperature, but also be able to set the temperature ahead of time before going home, a home to enjoy the warmth. Fourth, after-sales service continuity. For consumers in the purchase of products, especially bulky products, after-sales service is perfect and is an important factor. Professional companies generally have a complete service network and service system, not only to see the performance of enterprises and planning, but also is to look at business and professional qualifications, each link must be professional in order to ensure that the entire process of convergence of efficient, smooth. These are the purchase method of domestic boilers, at the time of purchase, not only to understand their true needs, but also according to different purchase models appropriate requirements of the boiler, the boiler using this feature was more in line with application requirements.
Fast boiler is a research and development, production and sales of high-tech enterprises, adhering to the "do professional, responsible for cleaning boiler systems integration provider" business philosophy, creating a series of excellent quality boiler equipment, such as WNS series gas (oil) boiler, SZS series of gas (oil) boilers, electric boilers and so on; second to none in the area of the National clean boiler. But we never had stalled the pace of independent research in recent years, the introduction of movable type boiler, after obtaining a favorable investment market.
