Definition of horizontal steam 75 ton fired boiler Horizontal steam boiler means a steam boiler horizontal design, according to the fuel divided into horizontal electric steam boilers, horizontal steam boiler fuel, gas steam boiler horizontal and horizontal coal-fired steam boilers. Horizontal steam boiler flue gas flow due to the long, slow smoke, high thermal efficiency, it is very energy efficient.
In accordance with article 1.2 13.3.6 to 13.3.8 "75 ton fired boiler design specifications" (GB50041-92): gas-fired boiler provided in the other buildings should be not less than 3 times the amount of ventilation, ventilation hour It does not include the amount of combustion air volume. Dangerous operating room and the like between the gas regulator, the amount of ventilation per hour, should be less than 3 times, when not meet the requirements natural ventilation, mechanical ventilation should be provided, and should be less than 8 air changes per hour accident ventilation times. Fuel pump and reservoir 45 ℃ flash point less than the underground tank of combustible oil, except that natural ventilation, the fuel pump mechanical ventilation 10 air changes per hour should times, six times per hour ventilation should depot mechanical ventilation. The above three are in each room in order to ensure exclusion of air and flammable hydrocarbon disposed a predetermined minimum ventilation rate.
Harbin Thermal Power Co., the main city of Harbin is the largest cogeneration business, the company bear the city's heating area of 24 million square meters, to provide heat supply for more than 400 agencies, enterprises and 140,000 residents. Currently, the company is actively respond to the latest environmental standards introduced in China, the group mobilized up and down, stepping up technological innovation, upgrading environmental protection facilities, the project is expected to complete upgrading coal-fired 75 ton fired boiler at the end of this year.
Harbin Thermal Power Co., the existing five boilers for heating and power generation: where to cogeneration units No. 7,8,9, and the other two hot water boilers. No. 9350 MW units which since 2017 was completed and put into operation, has achieved ultra-low emissions standards during construction. 7, No. 8 is 300 MW units were built in 2005 and 2006, these two units of environmental transformation began in 2013. Harbin Thermal Power Co., according to the latest environmental requirements, environmental upgrading facilities. First, soot emissions transformation, the introduction of advanced electric bag filter, followed by addition of sulfur, in addition to the transformation of nitrate, new burners in addition to the low nitrogen oxides of nitrogen, a wet desulfurization technologies in addition to sulfur dioxide. After four consecutive years of continuous transformation, 7,8 units in 2017, all the transformation is completed, achieve ultra-low emissions standards. For the two 116 MW hot water boiler was built in 2013, it has long been included in the transformation plan. Earlier this year preparatory work has been completed and environmental transformation has entered the bidding process in mid-October to start construction, completed renovation project at the end of December.
With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired 75 ton fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas-fired boilers, such as gas-fired boilers, are the most expensive to operate, gas-fired boilers need to be opened with gas pipelines, then, if there is no natural gas pipeline, and hope that the operation cost of the boiler is low, only the choice of fuel-fired boilers. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving.Free Chat
