(9)Combustion Adjustment method of Oil-fired Gas-fired Boiler

The combustion adjustment of oil-fired gas-fired boiler is successful and the load adjustment can be carried out after turning into normal operation. At this time, the combustion situation in the furnace should be observed frequently. If the atomization of oil and gas is not good, the flame jumps, the flame hits the furnace tank, and the exhaust temperature is too high or too low, the oil pressure, oil temperature, steam volume, air pressure and steam pressure should be adjusted in time to ensure the safe and economical operation of the boiler. The oil pressure and the pressure are related to the boiler load. The adjustment of the oil pressure is realized by adjusting the pressure of the burner or the amount of oil returned. The adjustment of air pressure is achieved through the opening of the valve. When adjusting a load, enter At the same time, the air volume adjustment must be carried out synchronously to ensure the reasonable match between the oil quantity and the air volume, so as to achieve the purpose of economical operation of the boiler.

The customer asked: what should I do after the fuel-fired chain grate heat transfer boiler china is put out?

Fangkuai Boiler Company replied: in case of quenching, the fuel supply of the furnace must be cut off immediately, the electromagnetic valve for gas supply (oil supply and return oil) will be closed, and then the fuel supply valve for each burner shall be closed. Operate quickly so as not to cause a vicious risk when fuel continues or resumes supply. At the same time, find out the causes of boiler quenching, remove the found faults, and make preparations for restarting.

PRODUCT INTRODUCTION fuel gas-fired chain grate heat transfer boiler china fuel gas-fired boilers and coal-fired steam boiler is not the same, gasoline and diesel and gas-fired burner must be poured into the fuel to the boiler furnace using a combustion chamber rather than grate facilities. Since the fuel gas-fired boiler is not easy to cause the fly ash lit, so no oil or gas boiler slag removal equipment. If mixed with air or exterminate within a certain range, it is introduced into the furnace petrochemical and gas easily the explosive. Thus, any gasoline and diesel and gas-fired boilers must be selected and automatic combustion control system. Compact boiler fuel gas, and the small boiler exhaust, drainage, control and auxiliary equipment installed at the distribution panel, and produce large and small boiler assembly. Fuel gas-fired boiler safety valve installation key point describes the installation of fuel gas-fired boiler safety valve sure to carry out in accordance with reasonable installation process, to prevent wrong and lead to risk. Fuel gas-fired boiler safety valve installation should pay attention to what matters? The following is a brief description: 1 oil-fired boiler safety valve having a lever bar to avoid self-weight and the mobile device guide body defining deviant lever, the spring valve lift handle and avoid the need for screw adjustment means random twist. 2. Rated evaporation than 0.5t / h gas boiler safety valve should be arranged at least 2, Rated evaporation gas boiler should be equal to or less than 0.5t / h, fitted with at least one safety valve. Separable economizer outlet and a steam superheater outlet valve should be installed. Sectional area of ​​the connecting pipe between the boiler safety valve 3. Fuel gas boiler can not be lower than the imported cross-sectional area of ​​the valve. If several valve mounted on each stub is directly coupled to the drum, the passage sectional area of ​​the stub is less than 1.25 times not all of the area of ​​the exhaust valve. 4. Oil and gas boiler safety valve should be mounted vertically in the height of the boiler drum and the header. Can not be mounted between the valve and the steam outlet conduit and the valve drum or header. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25 mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20 mm. 6. Fuel gas boiler safety valve should normally be established an exhaust pipe, the exhaust pipe should be directly connected security grounds, and there is sufficient cross sectional area to ensure the smooth flow of the exhaust gas. The bottom of the valve should be equipped with an exhaust pipe connected to the drain of a safe place. Valve must not be installed in the exhaust pipe or drain pipe.

Recently, Jinan City issued a "supplementary notice on accelerating the city's chain grate heat transfer boiler china-depth treatment of work-related" and formulated the following objectives.

I, on the in-depth treatment of boiler completion time. Low Nitrogen transformation and the transformation of the city's ultra-low emission gas-fired boiler biomass boiler to complete the appropriate time to relax, and strive to be completed in the end of June 2019, due to the commitment of heating (cooling) or involving people's livelihood and other support complex transformation process of the boiler furnace, indeed practical difficulties, completion time may be extended to the end of October 2019.

Second, on the in-depth treatment boiler standards. According to the "program tackling autumn and winter", the low nitrogen gas boiler after transformation, in principle, is not higher than the concentration of nitrogen oxides emissions of 50mg / m³, according to encourage the transformation of 30mg / m³. Encourage the transformation of biomass boiler with ultra low emissions coal-fired power plants.

Third, on the time-depth treatment of boiler arrangement. 2018 10 completed before the end inventory information verification, planning work; organize the implementation of the completion of the work before the end of May 2019; the end of June 2019 to complete the inspection work (due to heating and other disabled do not have to bear the acceptance conditions, available at the end of November 2019 before the completion of acceptance).

Fourth, on the information submitted to the work. Please ring the economy Zi [2018] No. 175 document complements the "Jinan City gas boiler investigation Summary Sheet" on or before October 12, "Jinan biomass boiler investigation Summary Table" to the Municipal Environmental Protection Bureau. On or before October 26, the "Jinan City Boiler depth management plan summary table", "Jinan hole sampling and sampling platform standardization construction unit summary table" and has completed the in-depth treatment of the boiler reconstruction proved supervisory monitoring report submitted to the Municipal Environmental Protection Bureau . Since the beginning of November, every Friday morning before 10:00 (for the first time submitted November 2) the progress of reform in-depth treatment of each unit case to the Municipal Environmental Protection Bureau.
