how much does a gas powered steam boiler cost
Matters needing attention in loading and installation of Gas-fired Steam Boiler
Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
Harbin City, Heilongjiang Province will continue to promote Blue Sky Battle Action Plan to increase emissions control work, it intends to phase out coal-fired boilers 1201 Taiwan, in accordance with national and provincial requirements, with the distribution area are classified Shi policy. Wherein the phase-out Zone has 9 to 42 tons of steam coal-fired heating boilers 10-35; 18 out of 35 tons of steam table (or a 29 MW) "peaking" heating boiler; built-up area outside the urban area out 10 tons of steam coal 1141 boiler units. Founded out of municipal coal-fired boilers special rectification work to promote the group, environment, housing construction, Industry and Information Department, respectively, to take charge of commercial, heating, industrial three "theater" phase-out of coal-fired boilers. District, county (city) government as the responsible body, one by one out of the implementation of the responsibility to determine the transformation of the way, to promote the phase-out. Gas companies, power companies and projects ahead of docking units, to protect gas, electricity supply and project construction. Planning, construction, urban management, public security and traffic control and other departments to provide maximum support and protection for countersigned examination and approval. Not included in the scope of elimination with 65 tons of steam coal-fired boilers, Harbin through online monitoring, supervision and monitoring, enterprise self-monitoring and "double random a public" supervision and inspection and other means to strengthen supervision, and urge enterprises to strictly enforce existing emission standards for excessive emissions will be punished according to law.
Steam boiler which automatically displays the instrument will encounter problems in accordance with the how much does a powered steam boiler cost fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boiler using the water level; in accordance with the constitution can be divided into vertical steam boilers, horizontal steam boiler, small steam boiler mostly single, double the return of the vertical structure, large steam boilers and more horizontal structure of three return. There lowland water or a display apparatus using the automatic water level when the water level in steam boiler water level is only a low level of installed devices, and even water pipes are too small; the water level or a Low level using the instrument, when the steam boiler is automatically displayed only one water; a water drain device, drain cocks no ground; on a drum water level is effective, other water damage; plug screwed on the fixed level; on tap water gauge leak, leaking; water false water level on the display unit; the drum water level in the two water gauge level of inconsistency; water is often broken glass; water gauge glass without guard; a water gauge glass plate not shown in the red line indicating the water level; water gauge glass plate is dirty, the water level observation is unclear. Steam boiler water level glass observation level of inconsistency and the main reason is unclear steam boiler for long periods of time rinse in running water, a daily maintenance is not carried out, resulting in water cock rust, gas, water and even the block, or insufficient packing or aging deterioration. False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water level due to misalignment connected; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the water level in the boiler and false priming. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water gauge is being cold draft at window glass, and glass pipe quality was poor. During the operation of the boiler, the water level was found is not clear, to shutdown immediately ultra-high water level, timely detection of problems.
What if there is wear and tear in the natural gas boiler? Detailed inspection is the key, as is fuel management. According to the operation condition and time of natural gas boiler, we can plan reasonable wear inspection. When using fuel, we strictly control the granularity of coal and limestone. The size of bed material should be strictly controlled. Boiler waste should be disposed of. The waste residue of the boiler must be treated before it can be discharged. Natural gas boilers should be installed where heat is used, easy to install. The hot pipe should not be too long. It should have a good insulation. The pipe shall be tilted properly from the hot water outlet to the end. The water supply source shall be equipped with a control valve. To discharge exhaust gases, the chimney of the natural gas boiler should extend to the outside and the outlet should be 1.5 to 2M higher than that of the boiler. If we want to reduce the influence on the water wall tube, we can adjust the air pressure and air volume properly, and effectively reduce the wear of the water wall. Check time is usually standby or downtime. Items to be examined include wall wear, furnace sealing and smoke leakage. In case of wear and tear, repair and welding are required to ensure the normal operation of how much does a powered steam boiler cost. Generally speaking, before combustion of natural gas boilers, fossil fuels, fossil fuels and bed and circulating materials should be filled in the combustion chamber at wind speed and strength. And stiffness of the air convection under full integration. Furnace bottom air device, inner core area upward. The movement in the outer ring region flows downwards along the water wall of the furnace, thus prolonging the residence time of the coal particles in the furnace. Mineral particles, a large number of ash powder and smoke contain a large number of fly ash particles, these continue to lead to rapid wear of water-cooled wall tube, make wall thickness wear thin, resulting in wear.
