fuel specification affecting natural gas boiler efficiency

Since December, the working out of Chishui City in Guizhou Province coal-fired fuel specification affecting boiler efficiency entered a crucial stage, ensure the completion of this year, the provincial environmental protection department issued a coal-fired boiler out of the task on time.

Chishui City Market Supervisory Authority on December 11 officially began governance, Union City Environmental Protection Bureau, City Comprehensive Administrative Law Enforcement Bureau, called the slow progress in phase-out coal-fired boilers companies and gas companies to warn interviews. It requires companies to plan prescribed time node coal-fired boiler renovation project, inverted construction, to ensure the smooth progress of renovation project.

From December 10 to 17, Market Authority law enforcement officers will be on hand daily supervision, dispatching five nine companies renovation project and construction schedule boilers, coal-fired boiler to ensure complete phase-out schedule.

Development history of oil and gas fuel specification affecting boiler efficiencys

Oil and gas boilers appeared late, and oil was first used in boilers in the 1930s, when it was used as an auxiliary fuel in coal-fired chain grate boilers. Due to the poor quality of the combustion technology and the fuel at the time, accidents in which the fuel suddenly extinguished during combustion often occurred, and thus were not actually used.

What is "green fuel specification affecting boiler efficiency" "boiler environmental protection" is a more general concept, a broad sense, refers to the boiler exhaust emissions, waste emissions and other environmental requirements of the load does not refer to a certain kind of single boiler. According to China's latest introduction of emission standards of air pollutants in some areas, Beijing, Zhengzhou, Xi'an and other cities of nitrogen oxide emissions have been reduced to the minimum standard of 30 mg / cubic meter. For fuel gas boiler, the combustion by the use of advanced technology or environmental burner configuration to achieve NOx emissions below 30 mg / m, belong to "green boiler." Electric boiler not to detail that the use of electricity as power and energy, waste no exhaust emissions, but are "environmentally friendly boiler" type. Environmental protection boiler they use FGR, premix combustion technology and other advanced reprocessing of flue gas, the flue gas heat reuse, reduce exhaust gas temperature. Can improve the thermal efficiency of the boiler, and reduce harmful substances in flue gas emissions, energy conservation and environmental protection to achieve social, economic double benefit. Fast boiler cleaning has many years of experience in manufacture and sale of boilers, and has developed a number of patented technology, production of boilers meet the most stringent air pollution emission standards in China. If you have to "green boiler 'needs or problems, can contact me directly, professional and technical engineers in real time to answer your questions.

How many calories Horizontal one ton steam fuel specification affecting boiler efficiency needs? 1 ton steam boiler, require 600,000 calories, biomass is the most economical fuel. 1 t of steam boilers, 600,000 calories needed, is converted into fuels: diesel 58kg / hour, i.e. cost of diesel and 466 / hour; biomass particles 150kg / hour, the cost of 165 / hour. 697 electrical degrees / hour, i.e. cost of electricity 697 / hour; gas 75m3 / hour, i.e. cost of natural gas 375 / hour; 120kg of coal / hour, i.e. cost of coal is about $ 120. As can be seen from the above, coal and biomass particles are the most economical. Wherein the combustion of coal is difficult to control, and the actual consumption costs considerably biomass particles. However, polluting coal boiler is very large, and the biomass boiler is both economical, and environmentally friendly. Accordingly, we can see that biomass pellet boiler is the best future direction of development of the industry boiler, the boiler will also become the industry mainstream.

Improve Your Boilers Combustion Efficiency

On well-designed natural gas-fired systems, an excess air level of 10% is attainable. An often-stated rule of thumb is that boiler efficiency can be increased by 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature. Boilers often operate at excess air levels higher than the optimum.

How Efficient is a Condensing Boiler? (2019) | GreenMatch

This means that the boiler efficiency rate can reach up to 90-91% at full condensation (80% from fuel burning and 11% from steam condensation). In a condensing boiler high-performing heat exchanger, the released gases are cooled to a temperature level that is almost equal to the water temperature from the reverse loop.

Boiler Efficiency | CleanBoiler.org

Higher water vapor losses when firing the fuel result in lower efficiency. This is one reason why fuel oil fires at higher efficiency levels than natural gas. To get an accurate efficiency calculation, a fuel specification that represents the jobsite fuel to be fired must be used.

INCREASING THE ENERGY EFFICIENCY OF BOILER AND HEATER

Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.
