One-Stop Solution for Generator After-treatment System and Load Banks
Flue gas denitration system, i.e. gas generating set exhaust denitration device (SCR selective catalystic reduction system) is the device which has the principle of converting nitrogen oxide (NOX) into harmless nitrogen (N2) and water (H2O) with catalyst. Requirement of NOX≤250mg/Nm3 in flue gas after denitration. 1. Harm of nitrogen oxide (NOX) In NOX discharged from generating unit, NO accounts for about 90%, and NO2 only accounts for a small
In the field of generators, silencers have the same effect on internal combustion engines as they have on engines in automotive and building applications. Both are designed to reduce the noise and exhaust emissions generated during fuel combustion. There are three basic designs for silencers: 1. The Reactive Silencer， its internal structure consists of three chambers connected by pipes, the exhaust noise bounces between the chambers, which reduces the output noise an
Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system used in diesel engines. What is Selective Catalytic Reduction? Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that injects a liquid-reductant agent through a special catalyst into the exhaust stream of a diesel engine. The reductant source is usually automotive-grade urea, otherwise known as Diesel Exhaust Fluid (DEF). The DEF sets of
HANLAN focuses on helping energy producers maximize plant performance and environmental compliance through innovative carbon monoxide (CO) and selective catalytic reduction (SCR) catalyst systems for gas turbine, boiler, and smaller-scale reciprocating engine generator plants. SCR is the predominant technology in nitrogen oxides (NOx) reduction in the power industry, with flue gas stream NOx reduction up to >90%. HANLAN has the experience with all of the details t
Selective catalytic reduction (SCR) systems have been utilized in various fossil fuel-fired combustion applications for decades as a means to control harmful emission levels. As gas combusts in turbines in combined cycle or simple cycle plants, nitrogen oxide (NOx) is formed—this can create intense environmental health hazards, including smog and acid rain. HANLAN excels at the design and installation of customized SCR equipment that will dramatically reduce the harmful emissions of your gas
Selective catalytic reduction (SCR) technology is the most critical technology to control nitrogen oxide (NOx) emissions. It is widely used in industrial flue gas denitrification such as thermal power plants and incineration plants, as well as diesel vehicle exhaust purification. The technology uses NH3 produced by urea, ammonia or liquid ammonia as the reducing agent, and the core is a denitration catalyst with good catalytic activity, high selectivity, high mechanical strength and stable op
Hebei Hanlan Environmental Technology Co., Ltd. invented "a generator set exhaust SCR denitration system approved by the State Intellectual Property Office. Diesel engines have always been due to their high thermal efficiency, low fuel consumption, good power, economy and durability. It is widely used in various power plants, but the harm of its main pollutant NO, has also attracted the attention of governments all over the world. The control of NO emission has gradually become a research hot
1. Biomass boiler flue gas characteristics (1) The concentration of sulfur dioxide and nitrogen oxide is low and fluctuates greatly; when burning pure biomass, the concentration of SO2 and NOx fluctuates between 120-250mg/m3, such as template, wood, and bark in the fuel, and the concentration of SO2 and NOx in the flue gas It fluctuates from 250 to 600 mg/m3. (2) The hydrogen content in biomass is relatively high, and the moisture content in flue gas is also high, reaching 15% to 30%. (
