The animal feed plant has a seasonal operation, but a relatively consistent load profile. The peak load is for 850 kg/hour of saturated steam at 8 barg (~650 kW see Figure 3). There is a much smaller load required for longer periods for miscellaneous process steam. The load is currently supplied by a very old light fuel oil (LFO) boiler. The load profile here facilitates an almost complete switch from LFO to biomass. 96% of the steam requirement would be covered by a 650kW biomass boiler. A small oil boiler, or built-in oil burner in the biomass steam boiler would be required to meet the smaller steam loads which would not be met efficiently by the biomass boiler. A straight-forward moving grate boiler with fire-tube heat exchangers can be used. The range of suppliers of biomass steam boiler equipment is limited below 1MW thermal as economies of scale are diminished below this level – a 650 kW boiler costs almost the same as a 1MW boiler.
Recently, Shaanxi Province, issued a "Boiler Air Pollutants Emission Standards" ( "Standards"), the "standard" in the concentration of air pollutants emission limits thermal power 6t boiler dealer russias and industrial boilers, we have developed a monitoring requirements.
Thermal power generation boilers including boilers of various capacities and various gas turbine capacity, fuel main types of coal, natural gas, oil, biomass, like other gas. Use gangue, oil shale, petroleum coke, fuel, sludge and other coal-fired power boilers reference emission limits fired boilers performed.
Industrial boilers including industrial boilers, various types of fuel capacity mainly coal, gas, oil, biomass, and so on. Boilers using coal, coal water slurry, coal waste, semi-coke, petroleum coke, oil shale and other fuel fired boilers performed with reference to emission limits. Using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.) with reference to the boiler exhaust gas boiler limits performed. Oil and gas dual-fuel boiler in accordance with the type of execution are oil-fired boiler and gas boiler emission standards. Other types of fuel mixed fuel boilers by performing more stringent emission standards.
There are large differences in the thermal efficiencies of different types of 6t boiler dealer russias. CBM szs series oil and gas boilers use a number of advanced technologies to improve boiler efficiency, such as spiral pipe, condensation technology, insulation technology, FGR flue gas recycling technology. The boiler's thermal efficiency can be as high as 98%
The compact wns series oil/gas boiler is available from 1 to 20 tph. The wns series products is a three-pass boiler with low combustion chamber loading. It delivers clean combustion with particularly low nitrogen oxide emissions. The three-pass design reduces the dwell time of the hot gases in the high reaction temperature range. This results in reduced nitrogen oxide emissions.
