commercial China hot and warm water boiler
Steam boiler using energy-saving, in strict accordance with standard operating procedures to avoid unnecessary loss of life of the boiler and fuel incomplete combustion of waste and pollution of the environment. When the boiler room is equipped with a number of boilers, the principle of allocation shall be high overall efficiency of each unit boiler load distribution.
A few months ago, Shandong Provincial People's Government issued the "Opinions on Further expand domestic demand and promote development of up short board", which refers to: As of 2020, invested 11 million yuan to complete 5.4 million renovation to replace it clean, let 55 % of villages to achieve clean heating.
In the "clean warm winter Shandong Province Planning (2018-2022 years)" is mentioned, in 2020 the provincial average clean heating rate of 70%, of which more than 20 million people in the city basically clean heating full coverage. 2022, the province's clean heating rate of over 80%. Among them, more than the city and county basically clean heating full coverage, the average clean heating in rural areas reached about 75%.
Jinan, Qingdao, Yantai City 3 converts kinetic energy as a province of old and new core area, to take the lead in forming an electrical heating alternatives such as clean coal-fired heating San basic pattern. Should be in accordance with the electrical power, should be renewable energy sources of renewable energy, the principle of the dispersed phase concentration and binding, while the priority of central heating, the positive development of other energy sources for heating air.
When gas boiler ignition, need to pay attention to what matters is the primary determinant of the ignition gas boiler started to master boiler ignition precautions to ensure the safe and stable operation of the boiler. 1, for gas-fired boilers, the ignition time if not successful, the need to purge the furnace flue, before a second firing. 2, in order to prevent a gas explosion, gas boilers not only to purge the boiler furnace and flue gas channel before the start, the need for a purge gas supply pipes. The gas supply duct media typically purged with an inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace flue with a certain flow rate is the flow rate of air. Case 3, in the rear of the boiler did not take anti-corrosion measures or condensation water collection, etc., gas boilers should avoid long-term operation at low load or low-parameter case. 4, the combustion gas boiler adjustment process, to ensure the quality of the combustion, it is necessary to detect smoke components, to avoid too high excess air and incomplete combustion. Generally, the gas-fired boiler during operation, the carbon monoxide content should be less than 100 ppm, and at high load operation, the excess air ratio should not exceed 1.1 to 1.2; under low load conditions, the excess air ratio should not exceed 1.3.5 , real-time attention should fireman switch case of a gas valve. Gas line not leak, if unusual circumstances, such as the boiler room abnormal odor, not open burners, ventilation should be checked to exclude odor, check valves, only put into operation is determined normal. 6, a gas boiler for liquid fuel with air, special attention should be ventilated boiler room. Because of severe liquid gases than air, in case of a leak can easily cause condensation of liquid and spread on the ground, resulting in a vicious explosion. 7, after a period of time or inspection line outage, when the single-column hydraulic machine into operation again, should open the vent valve, bleed time, deflation time should be determined according to the length of the pipeline and the gas species. If a longer boiler downtime, it should cut off the gas supply valve, close air release valve. 8, the gas pressure is too low and not too high, to be run within the set range, the specific parameter provided by the boiler manufacturer. When the boiler running for some time, found that the gas pressure is below the set value, should contact the gas company. Burner operation for some time, should be checked line filter is clean, as a lot of pressure drop, there may be too many impurities in the gas, the filter is clogged, washing should be removed, if necessary, replace the filter. 9, should comply boiler unit boiler manufacturers operating instructions provided by the manufacturer and the burner, and the description should be placed in a convenient place for easy, for inspection. When there are unusual circumstances and can not solve the problem, depending on the nature of the problem promptly contact boiler plant or gas company, to conduct maintenance by a professional maintenance staff. 10, shall comply with the provisions of the relevant gas. Not free to fire the boiler room, prohibited welding, gas welding and other operations in the gas pipe roadside.
Now what new boiler installation process is used: Each boiler unit has a different personal situation, may choose to electricity, natural gas, solar energy and other types of boiler equipment, but the boiler installation process is much the same. Well, now popular on the market boiler, how to install it?
