Black Gas Charcoal Hot Water Boiler

The main difference between the gas boiler and gas steam boiler What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.

Recently, Dezhou City, Shandong Province, has released the main points of pollution prevention and control in 2019, set specific targets and implement measures to control emissions of persistent pollutants SO2, NO2, to reduce the number of aspects such as severe pollution days.

After transformation of NOx emission in principle higher than 50mg / m3. Achieve a stable concentration of nitrogen oxide emissions rebuilt 30mg / m3 or less (that is, ultra-low NOx combustion requirements) can be appropriate priority in provincial subsidies make up ecological civilization prize funds.

5, continue to promote clean coal. Strengthen clean coal production, supply, construction and distribution system, and continue to improve the implementation of the subsidy policy, to ensure the timely distribution in place to protect the people warm winter. Bulk coal market to strengthen the comprehensive improvement of law enforcement, the implementation of three coal detection mechanism to prevent inflow of low-quality bulk coal, clean coal to ensure quality standards. 2019, on the basis of full coverage in clean coal, continue to promote clean coal.

6, strengthen high-pollution fuel combustion zone ban construction. Combustion zone ban, a ban on new or expanded high-polluting fuel burning facilities have been built to the deadline to switch to clean energy. Investigate and punish illegal construction, expansion and high-polluting fuel facilities are not completed within the prescribed period rectification behavior. Ban on burning coal for a total ban on the circulation area.

7, continue to promote clean heating transformation. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. Accelerate the pace of production, supply and storage of natural gas marketing system construction and gas storage facilities, improve air support capabilities. To develop multi-gas source, priority for clean heating, ensure safe and stable gas. Strengthen heating, gas facilities construction, expanding the central heating, gas, geothermal heating coverage. Accelerate the clean heating renovation project, before November 15, 2019 to complete the annual task of transformation goals. Complete power-generation coal, gas and other clean coal generation of heating transformation of the region, a total ban on bulk coal sales, to prohibit the sale and hoarding bulk coal, bulk coal to prevent the re-burning.

How pressure black charcoal hot water boiler the security work in Year 6 at night, is located opposite the old steam boiler certain aquaculture farm town of Rudong Ju Wang Tan explosion cause of the accident is operating a boiler operator improper. Such as shrimp farms in the South East of whitening, the use of the boiler is very extensive, mainly used for farming shrimp shed warming. Before many farms use steam boilers, higher risk, many farms put on a higher level of security pressure hot water boiler. Pressure hot water boiler is no risk, but it does not mean you can neglect of duty fireman. To regularly observe the water level to avoid low water level, the situation appears dry, otherwise there will be a certain risk, but will seriously reduce the life of the boiler using pressure hot water boiler. Boiler operator should note the following: 1, strict implementation of rules and regulations, seriously concerned to learn boiler expertise, and constantly improve the level, to ensure safe and economic operation of the boiler. 2, the pressure hot water boiler in use, organizations and individuals will be allowed to change the structure of the boiler, valves and piping system 3, before the predetermined succession visits to check a variety of devices, comprising: a water tank (hot water tank, expansion tank) , the amount of energy (boiler gas meter), a thermometer (temperature of hot water tank, the boiler water temperature of heat medium) and the like operation, when the shift operation to check the recorded inventory tool, and to learn more about the operation of the boiler. 4, take over staff as required, shift and provisions ahead of time to take over the boiler room to do the preparatory work, and to understand the operation of the boiler. 5, shift work were prepared in advance, be careful and comprehensive inspections and investigations, to keep the boiler running. 6, shift workers should take over personnel issues related to equipment operation, water quality and boiler blowdown, etc., without handing, transfer of personnel shall not leave their jobs. 7, keep the boiler running when the boiler clean, no dirt, no leakage, no rust and corrosion, carefully fill out detailed equipment maintenance records. 8, using the boiler room is one of the vital sectors of the boiler unit, in addition to the boiler room workers, leaders and security, defense, department managers, other unauthorized persons do not access inside. 9, prohibits storage of flammable boiler room and other debris and the like, loaded with a small amount of lubricant required, cleaning the oil drums, oiler, to be stored in designated locations, and pay attention to check whether the explosives combustion. 10, boiler room to be equipped with fire fighting equipment, carefully managed, it should not be moved or used for other purposes. 11, boiler room floors, walls, doors and windows keep clean. 12, competent leadership regularly, irregularly running records, sanitation inspection, identify problems and timely solutions. 13, at the stipulated time to work on time, do well shift recording, not just leave their jobs, leave something. 14, alcohol is strictly prohibited in the boiler room, drowsiness, gambling, fighting once found seriously.
