　　Frequently Asked Questions in Practical Operation of Biomass Hot Water Boiler

　　1. Biomass hot water boiler is not pressure-resistant, and the boiling water temperature does not exceed 90°C.

　　2. It is forbidden to install gate valves, reduce diameter, or block the air connecting pipe.

　　3. The pole of each module in the system software should be exhausted immediately.

　　4. When the system software runs out of water, water should be added immediately.

　　5. The water body of the boiler water and supplementary water should meet the requirements of GB1576-2001 "Industrial Boiler Water Quality".

　　3. Common problems in the firing operation of biomass boilers:

　　1) When the preparation work is completed, the circulation pump must be turned on first, and after the water circulation system in the system software network is up, it can be fired to increase the temperature to avoid excessively high temperature in the pot and vaporization.

　　2). Circulating pumps cannot be started with load, especially for large and medium-sized network systems. Be sure to prevent the motor from being burned due to excessive starting current. The centrifugal water pump should be started with the centrifugal water pump inlet and outlet gate valves closed until it runs normally. Then, slowly open the gate valve at the entrance and exit, and then open the hot customers to the outside world.

　　3) When opening hot customers to the outside world, the smart backwater gate valve is generally opened first, and then the power supply gate valve is opened, and the inlet valve connected to the supply and return pipes at the end of the system software network is closed.

　　4) During the ignition of combustion machinery and equipment, it is forbidden to use strong volatile raw material oil or flammable materials for ignition to avoid accidents.

　　5) After ignition, the temperature should not be increased too fast. The temperature of the furnace should be obviously increased under a slow flame to make the temperature in the pot rise evenly to prevent the temperature from rising too fast and destroying the furnace body. The heating time of raw coal boiled water biomass boilers is generally not less than 4h, gasoline, diesel, natural gas boiled water biomass boilers are not less than 1h; for light boilers, boiled water biomass boilers are not less than 1h; super heavy boilers boiled water biomass The boiler is not less than 4h.

　　Four. Common problems in winter application of biomass heating boilers:

　　In the severe cold winter, heating has long become one of the indispensable standards. Heating boilers of various models and specifications have given full play to their major functions. Among them, the biomass heating boilers that clean environmental protection have become the sales market. Popular machinery and equipment, as a kind of special equipment, need to pay attention to the following matters when applying biomass heating boilers in winter:

　　1. Before starting the ignition of the biomass heating boiler, check whether the gate valve of the heating system is open and whether the radiator of the high-rise residential building is full of water. If not satisfied, it will stop until the fuel is full. Check whether there are water seepage points in each system software. If there is water seepage, it should be repaired first.

　　2. If heating is terminated in winter, all the water in the biomass heating boiler and heating system should be drained to prevent frost breakage of pipelines and other heating equipment; when the weather is warming, the boiler must be blown, and the system software should be filled with water and tap water. Maintenance to prevent air oxidation of the system software pipeline, harming the heating furnace and pipeline

　　3. Maintenance must be carried out during the blowing period of the biomass heating boiler. After the heating furnace is repaired or annual audit, it is necessary to check that the hand hole, head hole and manhole nut can not be loosened, and check that the motor is converted to (from the cooling fan end). Look, it's the opposite direction).
