What is the maximum heat energy of biomass burner Z

our countryindustryThe main units of the factory adopt coal powder boilers and solid-state slag discharge methods. Therefore, all coal must be ground into very fine coal powder and suspended combustion is used. This combustion method produces a large amount of smoke (solid particles), accounting for more than 90% of the total ash content of coal. If calculated based on the commonly used calorific value of 5000 kcal and ash content of 20% Datong raw coal, and considering a power plant electricity consumption rate of 6%, the thermal power plant consumes 412 grams of Datong coal and produces 74 grams of solid particles for every 1 kilowatt hour of electricity produced. If the annual thermal power generation is 3.9 trillion kilowatt hours, with an average of 445 million kilowatt hours of thermal power generation per hour, the annual production of smoke (solid particles) from thermal power generation would be 33000 tons.The emergence of biomass burners has solved the dilemma of China's industry relying on coal combustion.

What is the maximum heat energy of biomass burner Z

The device has a wide range of applications:

Biomass burners are suitable for various thermal energy industries such as coating lines, electroplating plant ovens, boilers, small power plant boilers, industrial kilns, incinerators, melting furnaces, die-casting machines, drying equipment, kitchen equipment, drying equipment, food drying equipment, ironing equipment, paint baking equipment, highway construction machinery equipment, industrial annealing furnaces, fuel oil, gas, coal-fired large tonnage boilers, asphalt heating equipment, etc.

From the perspective of thermodynamic principles, biomass pellet burners have basically met three conditions:

One is the ability to fully burn fuel, converting the chemical energy in the fuel into heat energy more efficiently;

Secondly, it has good heat transfer and insulation effects, which increases the effective utilization of heat value and reduces the heat dissipation heat value;

Thirdly, waste heat can be effectively utilized to minimize smoke exhaust waste heat and other heat losses. At the same time, solid fuels can be gasified under high temperature and oxygen deficient conditions with reasonable control of the excess air supply coefficient. Therefore, in the research and design of the furnace, the lower part (gasification section) of the furnace is designed as a basically closed system, and the supply of air can be adjusted to achieve significant gasification effect of the fuel. With good gasification effect, it is necessary to ensure sufficient air support during combustion to ensure appropriate operating temperature. A secondary air intake ring (combustion section) is designed on the upper part of the furnace, and many secondary oxygen supply small holes are evenly distributed on the ring, greatly enhancing the full combustion of gasification fuel and making the combustion flame bright white. In addition, the gap size between the furnace and the bottom of the pot was optimized, and the matching size between the furnace and the bottom of the pot was found. This extended the swirling distance and time of the high-temperature flue gas flow in the furnace, avoiding the direct discharge of the burning flame into the flue, thereby reducing heat loss and improving thermal efficiency.

Preparation work should be done before using a biomass burner:

Before using a biomass burner, it is necessary to make preparations, strictly follow the operating instructions, and carefully inspect the areas that need to be inspected in order to ensure the normal operation of the biomass burner. So, what preparations need to be made before using the biomass burner?

1. Before using a biomass burner, it should be cleaned to remove dust. The boiler of the biomass burner should be taken out to clean the combustion residue inside the boiler. Then, the charcoal ash produced by the combustion at the bottom of the boiler should be removed. Finally, the boiler should be returned to its original position, and biomass pellet fuel should be added. Close the fuel tank cover and open the isolation valve.

2. Before restarting, it is necessary to conduct a detailed inspection to check whether the various components of the biomass burner are intact, especially the circuit. After connecting the power supply, check whether the circuit is unobstructed, whether the various indicator lights of the operating system are displaying normally, whether the water pipes are unobstructed, and whether the cold water in the water tank is sufficient. If it is not enough, add it in a timely manner. If the power indicator light prompts a warning or alarm display abnormality, the staff should immediately stop starting and report it to relevant technical personnel for maintenance in a timely manner.

3. If the power indicator light of the control system is normal and the machine is running normally after starting the biomass burner, the next step can be taken. Set the air supply button to a lower position, then add the bottom material, and the biomass burner can be officially ignited and started. Open the boiler door to supply air, close the boiler door to supply material, then adjust the windshield to medium, and gradually add biomass fuel to the boiler. Adjust the windshield gradually to increase the temperature inside the boiler. This gradual process takes about three minutes.

The above three points are the preparation work that needs to be done before using a biomass burner. Safety checks and preparation work must be done before use, which can effectively prevent the biomass burner from malfunctioning and shutting down due to various negligence and illegal operations. During work, we must always remember safety. Every operator of a biomass burner should carefully study the user manual and follow the correct methods and steps to operate the biomass burner, so as to ensure its normal operation and effectiveness.
