To start with the bed material is sand. Some portion is lost in the ash during the operation and this has to be made-up. In coal fired boilers the ash from the coal itself will be the makeup material. When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions.
It is quick to understand our side of the boiler, boiler and industrial furnace is Haimen sulfur dioxide, one of the important sources of emissions of nitrogen oxides and soot, boiler and industrial furnace to carry out remediation is to control total energy consumption, air pollution control, energy conservation an important measure low-carbon development.
Recently, Haimen government issued the "2019 Haimen boiler and industrial furnace remediation work plan" put forward requirements on the city's boiler and industrial furnace remediation work.
First, the target for the full year to complete the remediation boiler remediation tasks. DiBiao transformation of ultra-low emissions before the end of the year, the city's 2 sets of 35 tons of steam / hour or phase-out coal-fired boilers clean energy alternative to complete 2 sets of 75 tons of steam / h coal-fired boiler and 1 biomass boiler, completed 6 low nitrogen gas-fired combustion units transformation. Phase out coal-fired boilers to consolidate existing achievements regulation to prevent 20 tons of steam / hour resurgence of small coal-fired boilers.
Second, accelerate industrial furnace remediation. This year, the city's 32 industrial furnaces in accordance with the "out of a group, instead of a number, a number of governance" principle fully complete the comprehensive remediation tasks, promote the upgrading of industrial furnace and pollution reduction. And products of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln) and the like, according to cut-off high-pollution fuel combustion zone management requirements, the use of clean energy and heat plants, district heating Alternatively heat or the like.
Scheme requires 20 December, the district town organize and complete acceptance of the unit boiler and industrial furnace remediation tasks. Boilers have been removed embodiment physical treatment, use can not be recovered; coal-fired boilers use gas, electricity, light oil clean energy and stable operation of a month or more. Gas-fired low-NOx combustion transformation, the transformation of ultra low emission biomass boilers and coal-fired power boiler ultra-low emission transformation, to have construction contracts and construction unit transformation, after the completion of the transformation have qualified environment monitoring report. After the renovation of industrial furnaces to natural gas, electricity, light oil clean energy, the furnace can not be used and the coal and its products. Boiler and industrial furnace remediation in line with production safety regulations.
In the division of the gas boiler is adjusted, if secondary control of the wind speed is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Other irregularities when adjustment is not timely gas boiler load changes, the upper layer will not cool the secondary damper orifice such burners are burning.
Most efficiency trials conducted on this boiler have far exceeded the ‘Normal’ acceptable efficiency levels for boilers. Against an acceptable of 80-82% efficiency by the petroleum. Another distinctive advantage is the steam dryness of +5%.
Requirement design of tubes is made to make sure design tube can be used in certain temperature and pressure in steam boiler. Tubes are one pressure parts. These provisions should apply to any tubular pressure part that is either exposed over much of its length to hot gases for purposes of heat transfer or is directly butt welded to such aLearn More

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.Learn More
