3 ton biomass hot water boiler in vietnam
The characteristics of internal circulating fluidized bed boiler
The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:
1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.
2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;
3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;
4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;
5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;
6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.
7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.
Since more than six months since the boiler equipment, heating and hot water supply well, our technical staff also view real-time remote monitoring and control through the use of the boiler to the scene, Baiyun Quan Lake hotel management staff related to our technical staff gave very great encouragement and affirmation. --customer feedback
How to deal with water shortage in electric steam boiler machine in use for some time this or that problem will be serious delays in the progress of work, causing great inconvenience to the people, such as water shortage, this problem arises in the use of electric steam boilers after a period of water shortage in how people deal with how to solve it. Electric steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
The temperature difference between the wall surface of the vertical steam boiler steam is generated during the vertical steam boiler generates steam, and pressure in the heating, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the temperature of the lower wall, and wall thickness of the vertical bubble there is a temperature difference between the walls, i.e., the inner wall temperature of the bubble is higher than the temperature of the outer wall, the wall temperature is higher than a temperature lower wall, an outer wall and inner wall temperature is higher than the temperature of the inner wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature of the lower wall , the wall temperature is higher than the outer wall temperature, the wall temperature is higher than the temperature at the wall, the inner wall temperature is higher than the outer wall temperature. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass 3 ton biomass hot water boiler in vietnam, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. In order to prevent excessive thermal stress, it is necessary to slow the vertical steam boiler booster. Vertical steam boiler ignition and boosting process conditions steam parameters, each component level and also changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange closely monitor vertical steam boiler various instruments directive professionals change. Since the vertical steam boiler water temperature continues to rise, the metal wall temperature of the bubble and the evaporator heating surface begins to rise at any time, it is necessary to pay attention to temperature and thermal stress of thermal expansion of the bubble, since the bubble wall thickness is relatively thick, so vertical the main problem in the steam boiler heating thermal stress. At the same time, also considering the overall thermal expansion problems, especially vertical tube steam boiler heating surface, since the wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused.
