tph water boiler order
1. Reduce the heat loss of boiler exhaust:
(1) The air leakage rate of the high air preheater, especially the air leakage rate of the rotary air preheater;
Large-scale CFB biomass boilers
Circulating fluidised bed (CFB) boilers are ideal for efficient power generation, capable of firing a broad variety of solid biomass fuels in applications ranging from small combined heat and power plants to large utility power plants. My company has progressively advanced and scaled up CFB technology for biomass firing since the 1980s, starting from small multi-fuel boilers in pulp and paper mills to Advanced Bio CFB technology firing a range of biomass fuels.
SZS gas steam boiler 1 product advantages, advanced boiler design: corrugated furnace decoration, strong interference low ripple furnace flame, greatly improving the heat transfer coefficient, reducing the temperature of the exhaust gas boiler thermal efficiency up to 90%, reducing equipment thermal expansion and contraction caused by the living. 2, mechanical design of advanced boiler: the front smoke box design with a hinge connection, with the smoke box access door, making maintenance and cleaning easier. Peephole rear of the boiler is provided with flame, combustion furnace can be observed. 3, the heat insulation efficiency design: The use of lightweight aluminum plates incubated measures to greatly reduce heat loss, transdermal topical stainless steel sheet, to improve the appearance quality. 4, the world's most advanced combustion machine: the internal combustion engine is the main component of the boiler. It directly affects the quality and performance of the boiler thermal efficiency, operating cost, reliability, and other indicators. This type of boiler using the world's most advanced burner, Leaho and so on. German or Italian brand WESO Bite brand gas burners. 5, safe use of advanced safeguards: Under normal circumstances, the machine automatically adjusts output pressure in the combustion boiler, the water temperature reaches the set value, the burner is automatically stopped when the temperature is below the set value, the burner starts automatically. When the burner with air inlet gap occurs, ultra-high temperature, overpressure, and other foreign matter suction phenomena, combustion is stopped automatically, fault lamp is lit, the programmable control means immediately stops the output of the fuel, the furnace only after troubleshooting before restarting N. 6, the world's most advanced combustion machine: the combustion chamber has an automatic purge function, each time before ignition, will be strong winds sweep for 1 minute. Residual combustible gases in the furnace, preventing the occurrence of knocking when the ignition phenomenon. Meanwhile, the boiler cigarette feature built-blast doors. When the furnace deflagration, blast doors automatically open the lid, the combustible gas enters the cigarette. Through the chimney into the atmosphere (rather than into the boiler room to avoid fire accidents), automatically shut down after the explosion-proof door release pressure to ensure the safe operation of the boiler. 7, advanced processing and testing equipment, the feed material under the boiler plate shears are made, changing the original cutting material HAZ shortcomings; rolled steel plate with four stick cylinder machine more reliable processing quality; drum all automatic submerged arc welding, non-destructive testing, pipe welding by the tube plate and the fireworks are tungsten arc welding, ultrasonic testing time control of welding quality.
Since the beginning of 2017, Qingdao City, Shandong Province to carry out the transformation of governance coal-fired boiler, as of today, has a total payment of coal-fired boiler exhaust gas treatment and transformation subsidies of 240 million yuan in 2014 to 2016 for the sum of the total grant funds, the city this year We will continue to invest 350 million yuan for the renovation subsidy ultra-low emission coal-fired boilers.
Statistics show that January-October 2017, Qingdao City, "blue sky, starry" increased by 16 days the number of days year on year, totaling 289 days, accounting for more than 95% of the total number of days throughout the year, fine particulate matter (PM2.5), respirable The average concentration of particulate matter (PM10) reached 35 micrograms / cubic meter, 70 micrograms / cubic meter, an improvement of 16.7%, 14.6%, the highest in the province for the past five years, the highest level in the same period, the air quality in the first half to get the provincial government incentive funds 16.77 million yuan.
2014-2016, municipal finance coal-fired boilers and efficient treatment and transformation project grants 230 million yuan, began to be 100,000 yuan subsidy per ton of steam coal-fired boiler exhaust governance 2016 (Note: in 2016 began to carry out boiler subsidies, continues to the present is still the case).
