【Characteristics of Biomass Steam Boiler】

　　Biomass steam boiler runs environmentally friendly, saves fuel, automatically feeds and discharges slag, blower and induced draft fan frequency conversion adjustment, boiler automatic operation, can automatically adjust the amount of fuel according to load changes, and the steam output is stable. With multiple protection and alarm measures such as pressure, water level, exhaust gas temperature, etc., to ensure the safe operation of the boiler. Biomass steam boilers led by Shandong Duole are boilers advocated by the society, and the state will strongly promote them. Bio-steam boiler and boiler combustion technology. The biomass steam boiler effectively reduces energy consumption, reduces the emission of carbon dioxide, sulfur dioxide and nitrogen oxides, improves the environment, and is an important measure to improve the haze weather in the north.

【Working Principle of Biomass Steam Boiler】

　　Biomass steam boiler heating equipment (burner) releases heat, which is first absorbed by the water wall through radiation heat transfer, and the water on the water wall boils and vaporizes.

　　A large amount of steam is generated into the steam drum for steam-water separation (except once-through boilers), and the separated saturated steam enters the superheater, and continues to absorb the heat of the flue gas from the top of the furnace, the horizontal flue and the tail flue through radiation and convection, and superheat the steam Reach the required working temperature. Power generation boilers are usually equipped with reheaters. Biomass steam boilers are used to heat the steam after the high-pressure cylinders do work, and the reheated steam from the reheater goes to the middle and low-pressure cylinders to continue doing work for power generation.

【Precautions for Biomass Steam Boiler】

　　1. Please follow the product manual for the specific operation of the boiler to ensure the safety of operators and equipment.

　　2. Before starting up, check the power supply, voltage, water source, whether there is any abnormality in the gas, close the drain valve, open the water supply valve, check whether the flue is unobstructed, check the pressure of the furnace body and the working condition of the water supplement pump, check the closed condition of the gas pipeline interface, and close the gas valve Pre-ignition once to confirm that the motor is rotating. Check whether the water pump is stuck. If the pump is stuck, remove the rear cover of the fan blade and turn the motor shaft to a flexible state to start the machine.

　　3. When you are overhauling the boiler or replacing parts, please cut off the gas and power supply to avoid danger caused by live work.

　　4. The electric control box, burner, water pump motor and other parts should be protected from moisture and water to prevent burnout. The boiler should be kept clean.

　　5, the safety valve should be regularly inspected for flexibility, and the lever of the safety valve should be quickly pulled once a month to check the flexibility of its take-off and seat return. The safety valve should be checked regularly at the local technical supervision bureau every year
