What are the three common long life fired 300 kg per hour boiler 0 7 mpa combustion? Urban coal-fired boiler has been difficult to solve, because especially small coal-fired boilers type cluttered and more widespread particularly difficult to handle. On the one hand burning low power, on the other hand is more a waste of resources. Under the requirements of environmental protection requirements, many cities in the relevant part of the requirements necessary gas (oil) boiler retrofit or replacement of 10t / h coal-fired boilers. The transformation of the former needs to focus attention to the following questions: whether the site is useful region of central heating boiler heating of small alternative program. The useful life and corroded boiler, if the boiler by Zhengzhou fast boiler or other professional testing organization to determine the useful life of less than five years, the transformation of value is not high. Determine whether the laying of gas pipeline convenience, liquefied petroleum gas or other fuel supply and transportation issues. Comparing the cost of renovation and equipment manufacturers advantages and disadvantages, in determining the needs of the transformation plan in compliance with these principles. Selection of fuel. Under the premise of fuel sources have, the most economical natural gas pipelines, liquefied petroleum gas, followed by a final light diesel oil. Also, consider the surrounding environment from fire and explosion safety. In general, the system and the soda boiler pressure parts and preferably not modified to adhere to the original power, are demand, under conditions not substantially change the pressure member, than the original power increased by 10% to 20%. Boiler pressure parts for major changes in the program desirable. The transformation process is necessary to ensure the safety of boiler pressure parts of (mostly small commercial general pressure boilers), followed by incineration system to ensure the safety factor, the decline in the risk of explosion, fire accidents. Recognize the transformation of the planning process, in a timely manner, the environmental protection, the gas company, fire department, urban construction and timely communication with the boiler section to monitor and ensure the transformation plan can proceed smoothly. When the boiler is burning way during boiler selection will take into account an element, the following three common boiler burning approach advantages and disadvantages brief analysis cf: 1 Decentralized incineration strengths: this way is not burning premixed, but the gas nozzle mouth dispersed with each other, and then burning it. Incineration relatively simple way, as more stable as compared to the flame. Disadvantages: Due to a longer flame, it is prone to the phenomenon of incomplete burning, more carbon monoxide and nitrogen oxides will occur, it is not conducive to the use of full-fired boilers, to improve the thermal power of the boiler, and the boiler emissions standards are difficult to reach. 2. premix approaches incineration advantages: premixing air and gas, a multi-way heat radiator, to improve the strength of heat transfer. Strengths of this approach is that the burning of the burning flame is more clear, and the higher heating power. Disadvantages: incineration requires precise ratio premix burning rate is fast, uniform burning radiant heat transfer full power high flame temperature below 1200 deg.] C, all NOx completely burned and the occurrence of low flue gas temperature, condenses, good heat recovery and high power. 3. No flame burning incineration space before incineration approach uniform mixing with the gas in the gas boiler. When using this approach, in the process of incineration gas in the oxygen demand is not made in the ambient air demand, only needs to achieve instant complete incineration air mixture reaches the incineration zone. Approach in the selection of incineration, incineration demand for the advantages and disadvantages of different approaches, carried out mutatis mutandis selection, a good way is also advantageous burning boiler to reach plenty of incineration, thermal power increase, decrease the role of emissions, and therefore, it is important to choose carefully.

Biomass long life fired 300 kg per hour boiler 0 7 mpa case:

The animal feed plant has a seasonal operation, but a relatively consistent load profile. The peak load is for 850 kg/hour of saturated steam at 8 barg (~650 kW see Figure 3). There is a much smaller load required for longer periods for miscellaneous process steam. The load is currently supplied by a very old light fuel oil (LFO) boiler. The load profile here facilitates an almost complete switch from LFO to biomass. 96% of the steam requirement would be covered by a 650kW biomass boiler. A small oil boiler, or built-in oil burner in the biomass steam boiler would be required to meet the smaller steam loads which would not be met efficiently by the biomass boiler. A straight-forward moving grate boiler with fire-tube heat exchangers can be used. The range of suppliers of biomass steam boiler equipment is limited below 1MW thermal as economies of scale are diminished below this level – a 650 kW boiler costs almost the same as a 1MW boiler.

Comfortable life of people is inseparable from the northern winter heating long life fired 300 kg per hour boiler 0 7 mpa, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).

How to prolong the life of the long life fired 300 kg per hour boiler 0 7 mpa low nitrogen Now, with demand increasing in industrial production, the traditional boiler has been completely unable to meet the higher requirements of these industries, and domestic professional low nitrogen boiler manufacturing enterprises not only to bring Conveniently, they also save some costs, it is widely used in various fields, but how we should extend the life of low nitrogen boiler it? 1: Check the power to do maintenance work because of the low nitrogen boiler acts as a very important role in the production of industrial, so companies before use, you must first do a good job security and troubleshooting, power checks and maintenance work, in order to ensure users personal safety and efficient operation of the boiler, Also, the various parts of the device to check all aspects of the work, to make the life of low nitrogen boiler becomes longer. 2: the device to keep dry and regularly check the patency of the smoke tube boiler when low nitrogen after completion, the operator should be promptly cut off the power, and when the apparatus until the temperature drops, dust and dirt need to clean the housing, the boiler also placed in a dry and ventilated place, the next device in order to ensure the normally open, secondly, due to the low nitrogen boiler exhaust gas is carried out primarily by the threaded pipe, so that the operator using the device after this, smoke tube should be cleaned regularly to avoid being blocked by dust and affect their effectiveness. 3: To add a lubricant for the component devices on a regular basis when low nitrogen boiler running at low load, disk prison staff must focus on and strengthen the analysis of each instrument, abnormal should promptly make the right judgments and treatment, in order to ensure the normal operation of the boiler and to extend the life of the enterprise in order to create greater economic benefits, in addition, also for the various components of low nitrogen boiler regularly add the oil in order to reduce the resistance of boiler operation and to improve its production efficiency. All in all, in addition to the user to do routine checks and maintenance work power, we should also keep drying equipment and do regularly check smoke tube patency, to make good quality and low prices of low nitrogen boiler to have a better use effect and longer life for enterprises to win the biggest economic benefits.
