The CFB domestic pellet boiler with hopper manufactured in Namibia has been based on an internally recirculating circulating fluidized bed system. Discussions with manufacturers indicated that this system is best suited for the application which involves a low moisture content fuel.

Fangkuai domestic pellet boiler with hopper removal and its pre-start requirements to learn and understand the boiler, can be a variety of ways and forms, as long as they can master the relevant knowledge content, can be. So, for this purpose, and in order to have a comprehensive understanding and understanding of the boiler, next, the boiler will be studied, so that you can also obtain some new knowledge and good use of it. 1. Is there a requirement for the feed-in speed of the boiler before start-up? Before the boiler starts, if the boiler is hot water boiler, then, there are some requirements, its specific is: hot water boiler before the start-up water intake speed should not be too fast, winter Seasonal water intake time should not be less than 4 hours, other seasons are 2 to 3 hours, the initial influent speed should be slow. In the case of a cold boiler, the inlet water temperature should be in the range of 50 ℃-90 ℃. 2. How to remove the boiler? Boiler demolition, it is conditional, not all boilers can be carried out. If the boiler has been in use for more than 10 years, demolition is not allowed. In addition, the boiler removal steps and procedures are as follows: the boiler must be within the inspection period of validity or through the local boiler inspection office to pass the inspection-to the boiler location quality supervision bureau special facilities to handle the transfer Installation application-boiler new installation site quality supervision bureau special unit handling transfer notification-boiler inspection center installation inspection qualified-put into use. 3. Which boilers are normal pressure boilers? Why use high-temperature condensate? From a professional point of view, there must be hot water boilers in atmospheric boilers, but not steam boilers. However, not all hot water boilers are atmospheric boilers. When the conveying distance is close, the heating area is smaller or the required hot water temperature is not higher than 100 degrees Celsius, the atmospheric pressure boiler can be used. When the boiler is running, it is used to produce steam through industrial water and coal-based energy. When steam releases some of its heat energy, it becomes high-temperature condensing water. If high-temperature condensing water is recycled as boiler recharge water or secondary flash steam is used, the industrial water and fuel can be saved, and then the flue gas emission of boiler can be reduced. Therefore, high-temperature condensing water will be used in boilers.

How to control the temperature of the gas domestic pellet boiler with hopper boiler worker was required configuration of boiler equipment at run-time staff, they must not only ensure safe operation of the boiler, but also to maintain sustainable and stable operation of the boiler. Moment, we can see that intelligence is popular, gas boiler has entered the era of intelligent, by installing an automated control system, the boiler can achieve all-weather operation, without staff on duty to reduce the labor burden fireman personnel. So, these intelligent gas boiler automatic control is how to do it? In boilers with automatic control systems, built-in temperature sensor, corresponding to our eyes These sensors work in the case of boiler operation can be transferred to the boiler by means of the controller data. For example, a boiler with a set temperature of 55 ℃, a temperature sensor in the boiler furnace temperature acquired at this time is 40 ℃ boiler runtime. After sending the temperature data to the controller determines the control temperature is far from the set temperature, so the controlled state of the burner fire continues to heat the water in the boiler. Boiler continues to operate, the temperature sensor and temperature data are collected continuously transmitted to the controller, as the heating temperature gradually rises to the combustor 53 degrees. At this time, by setting the temperature controller and the current temperature of comparison, determining the water close to the set oven temperature, thus lowering the flame and pilot burner. As the temperature is set closer to 55 ℃, the burner can be based on the actual frequency of the heat demand, precise control of the size of the flame, by gradually close, maintaining the temperature at 55 ℃. When the heat demand changes, the flame will make a corresponding change in the boiler only works to maintain the temperature of the state, to avoid unnecessary waste of resources. Conventional boilers commonly used three-stage fire (fire, fire, small fire), for certain situations, such as the heat demand is just larger than the fire but it is far from the point where the fire needs heat, in which case the controller will continue to use fire heating, when the temperature will rise rapidly and soon exceeds the set temperature. At this time, the controller detects the water temperature has been exceeded, then control of the burner to a small fire. However, a small fire can not satisfy the heat demand, the boiler water temperature will drop at this time, the moment down to a certain extent, the controller turn a small fire into the fire heating. Volatility in this way compared to frequency control, not only the temperature, but also a certain phenomenon empty burning waste gas.

Before the opening, Xiao Bian would like to ask you, for the "domestic pellet boiler with hopper" the vocabulary, what concept? Heavy shell? Dark boiler room? Or the dusty it? In the fast boiler, all this will be broken. Into the fast side, the first thing is 120,000 square meters of factory area, 6,000 square meters of clean boiler test center, you will inevitably get lost. But now do not worry, we launched a corporate panoramic VR, sweeping away mobile phones, travel all know.
