We would recommend your biomass boiler has at least an annual maintenance service. Like anything if you maintain your boiler correctly it will last longer and perform better. Biomass boilers burning even the most difficult of materials can operate unattended, but weekly inspection visits are required to carry out a visual inspection of the boiler and fuel feed system, to check the lubrication of bearings and to empty the ashbin.
As a large enterprise specializing in manufacturing boilers, ZOZEN...
A biomass boiler is a boiler designed to burn solid fuels classed as biomass. Such boilers can be supplied to burn every form of biomass from woodchips, wood pellets or logs to waste agricultural materials such as straw and grain husks, olive kernels, rice and the dust from any of these including sawdust. Boilers need to be designed to burn specific materials, with any given boiler able to burn a limited range of biomass.
ZOZEN biomass-fired boiler has wide fuel adaptability, is suitable for a wide variety of biomass fuels including biomass particle, wood chips, palm shell, straw and so on. The engineering technique personnel of ZOZEN optimized the design of the feeding hopper, the length and width of the fire grate, rotary speed of gearbox, 1st and 2nd air ratio, vapor orientation and position, etc; the above upgrades ensure the high thermal efficiency and stable operation of the boiler.
1. Rational air distribution, supply sufficient and rational air by region; 2. Appropriate furnace temperature;3. Suitable air turbulence and mixing in furnace;4. Fuels remain long enough on chain grate and in the furnace;5. Keep a reasonable distance between the fuel hopper and the flame fronts to avoid igniting fuels in the hopper.The biomass-fired boilers are optimally designed according to the characteristics of different biomass fuels. ZOZEN will customize the biomass-fired boiler for ...
For the selection of heat fluid boilers, first step is to determine several parameters: thermal power in the process, the oil temperature, and the use of waste heat.There are several methods for determining the boiler's thermal power:1. Calculation. According to the specific heat capacity of the material to be heated, the heating temperature difference, the processing amount per unit time, etc., the thermal power is equal to the product of the above three points, and the calculation result considers a certain margin amount as the boiler capacity.2. The sum of thermal power in the process equipment can also be used as the basis for the heat power.3. Refer to the experience of the same industry to increase or decrease on the basis of peers.4. If steam heating is used, it can be converted into heat transfer oil of the same tonnage and the capacity is appropriately reduced.The determination of the temperature of the heat transfer oil can be determined according to the characteristics of th
Question details (performance):Black smoke happens during operating. Answer: Fault reason:(1) Insufficient air volume, improper air distribution, low furnace temperature: boiler usually equipped with air preheater, but when the air preheater has leakage, hot air flow doesn't satisfy the need of burning, smoke will happen.(2) In the case of stalling situation in full automatic oil-fired boiler: significant increase of furnace negative pressure, no flame can be seen from the inspection hole, steam pressure and steam temperature drop, the steam flow decreases sharply. The water level drops suddenly and then rises sharply.(3) Incomplete fuel burning: this is the main cause of boiler smoke, in the operation, some combustible gases such as carbon monoxide, hydrogen, methane will be generated in addition to carbon dioxide, sulphur dioxide, water vapor and oxygen, nitrogen, etc. during incomplete combustion. They burn and generate black smoke. Incomplete combustion of fuel will not only lead t
Question details (Performance):There is no feeding machine between hopper and # 0A/B belt, which causes unstable feeding and feeding amount cannot be controlled, during running, big amount material presses on belts which affect normal operation of the belt.Answer: The cause of the problem: Because the toughness of the biomass fuel is bigger, the proportion is small, material level should not be too high, otherwise it will occur block, so conveying system is normally running 24 hours, moving parts are easy to wear and cause high failure rate; also the length of the cut grass is difficult to guarantee its length between 8 ~ 15cm, and it is easy to get stuck in the feed machine before the furnace and it is difficult to clean, which has a great impact on the load of the boiler. Troubleshooting: 1. To reduce wearing and expand the service life of equipment, general motor adopts variable frequency motor, slow down the running speed, to control the rate of fuel feeding, make material's stacki
