coal fired boiler in vietnam
Gas-fired steam coal fired boiler in vietnam steam boiler and gas accounted for half of the market at any time, more and more national attention to environmental protection, gas steam boiler has been hit hard. In contrast, gas steam boiler by many users of all ages. In recent years, also vigorously promote the use of gas-fired boiler. Gas-fired steam boilers What are the benefits? Let us discuss with you today. Gas-fired steam boiler steam boiler and gas market accounted for half of the market, showing a trend of resistance of court, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: Obviously, in terms of technical gas boiler and auxiliary aids far ahead of the gas boiler, and is equipped with a special gas burner. 1 ton steam boiler, for example, gas boiler about 30% higher than the gas boiler. 2. Construction cost: This cost mainly from the boiler room. As more gas steam boiler auxiliary equipment, boiler house construction should invest more money. Less gas boiler auxiliary equipment, automatic control operation, with automatic alarm and automatic protection, saving the cost of housing, safe and reliable. After natural gas pipeline, the burner will automatically supply, cost-effective employee. Gas boilers also need to pay some wages, because they need to participate in coal plan. 3. fuel costs: You can clearly see this by looking at the actual specific fuel prices at each location. The fact is that the amount of coal burned per hour is much higher than the amount of gas. 4. environmental costs: In the need to protect the environment, the review of the gas boiler are becoming increasingly stringent. Because of the economy, environmental protection and energy as well as government policies, gas steam boilers more and more widely used.
After the coal fired boiler in vietnam put into use, such as the hotel responsible person to give us feedback: fast boiler advanced product design, simple and intuitive operation, the most critical is energy saving, low NOx emissions, can be used in the Beijing area. Compared with other boiler brands, fast Boiler made us worry. --customer feedback
Today I saw that when the capacity is the same, the furnace of the oil-fired coal fired boiler in vietnam is smaller than that of the coal-fired boiler. Why? The specific reasons are as follows: the size of furnace volume, after the boiler capacity is determined, mainly depends on the volume of heat load. The size of the volumetric heat load is mainly determined by the type of fuel. After the fuel enters the furnace, it will take a certain amount of time to burn out. Fuel is usually required to burn out before it leaves the furnace. It is obvious that pulverized coal will burn longer than oil, that is, the flame of coal combustion will be longer than that of oil. In order to ensure the long-term safe operation of the boiler, it is necessary not only to prevent the slagging of the boiler, but also to make the temperature of the flue gas at the furnace outlet begin to change compared with the ash in the flue gas The temperature is 50 ℃ lower than 100 ℃ to prevent slagging at the furnace outlet and subsequent convection heating surfaces. The ash content of coal is more than that of coal-burning furnace, and the flue gas temperature of furnace outlet is 1050 ℃ and 1100 ℃. There is no danger of slagging in the furnace because of the low ash content in the oil, and do not consider the slagging problem of the slag discharge tube at the exit of the furnace, so the smoke temperature at the exit of the furnace can be higher.
In modern industrial production, the coal fired boiler in vietnam plays a very important role, but it is also easy to scale or suffer corrosion damage. Therefore, boiler heaters need to clean the relevant boiler equipment in time under this condition, in which the non-cleaning agent which has the most outstanding performance and practical effect is the non-cleaning agent. When the heating system is replaced, cleaning agent must be used to clean the pipe to eliminate the inner wall debris so as not to affect the heat transfer efficiency and service life. In use, it should be carefully checked, water-proof, acid, alkali and low boiling point leakage into the use system, and add a filter device to prevent mechanical debris into the system, to ensure that the oil is pure. Degree According to the requirements of the grade and the heat use process, all kinds of high temperature brands are selected correctly, and the regulations of the Safety Technical Supervision rules for Organic Heat Carrier Furnace are strictly complied with, and they are used correctly. The high temperature of boiler is suitable for heating equipment such as coal burning, gas, fuel oil heating furnace as carrier, electric heating reaction kettle and other heating equipment, such as expansion tank, oil storage tank, other safety components and temperature control instrument, etc., so as to ensure safe operation. The purpose of the boiler cleaning agent is to quickly remove the dirt and carbon accumulated in the internal pipes and heat exchangers of the boiler. Then we also have requirements for cleaning agents. We must not harm our metals. Heat transfer surface, requires no residue, complete dissolution, and must be easy to operate, as long as ordinary personnel in accordance with the use of procedures on the operation. The requirements of our Fangkuai boiler for boiler cleaning agent are: low energy environmental protection, five poisons odorless, non-flammable, small irritability, can be discharged directly after cleaning.
