The water vapor partial pressure may know, 10t atmospheric pressure boiler uzbekistan exhaust gas dew point temperature is generally 55 ~ 60 ℃. We reduced by the refrigerant medium (e.g., cold water, cold air, etc.) to a flue gas temperature of flue gas temperature below the dew point, the condensed water vapor in the flue gas can be recovered sensible heat and latent heat of the flue gases at the same time. Calculating the thermal efficiency is low calorie fat conventionally as a reference, is included in the latent heat efficiency of the boiler after steam heat may exceed 100%. And because the water vapor condensation process condensed water may absorb a portion of the harmful gases (e.g., S02, NOx, etc.), reducing the pollutant emissions, environmentally friendly. Per standard cubic meter of combustion gas can be generated in Northern approximately 1.6kg of water, gas boiler fuel consumption of about 0.7MW 80m3 / h, if half of the generated steam is cooled down, may be generated 80 × 1.6 x0.5kg / h = 64kg / h of water, you can see the amount of water available is considerable, if taken measures to make use of this part of the water, the water shortage in some areas will have a positive effect.
It must be noted: When someone is working inside the drum, the drum must have someone outside monitoring. 2, before entering the combustion chamber or flue work must be taken ventilation, anti-virus, fire, explosion-proof measures. And the total flue chimney flue or other operation of the 10t atmospheric pressure boiler uzbekistan is connected to the gates are closed tightly.
Precautions gas steam 10t atmospheric pressure boiler uzbekistan Use: Gas-fired steam boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, are dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.
Expected by the end of this year, Jiangsu Province, the province will complete the ultra-low emissions below 100,000 kilowatts coal-fired units. It's Jiangsu Province, following more than 100,000 kilowatts ultra-low emission coal-fired units in 2017 renovation, energy-saving and environmentally friendly coal a "first in the country."
According to statistics, Jiangsu Province in energy consumption, accounting for over 60% of coal, which accounts for coal and coal consumption sticking. Industrial emissions of air pollution is the bulk, ultra-low emission power plants, clean coal is to enhance efficiency, promote air pollution control "top priority."
According to the deputy director of Jiangsu Provincial Development and Reform Commission Energy Bureau, Jiangsu Province coal units in the national energy conservation program first started, the fastest progress. In the coal transformation "mentioned standard extended surface" advancing, Jiangsu Province by the national requirements of more than 300,000 kilowatts stand-alone, single expanded to more than 100,000 kilowatts, 100,000 kilowatts this year covering the following units. In order to promote energy saving coal-fired power plant, Jiangsu Province, also the first start price subsidies, together with local award and subsidy, enterprise since the vote, five years invested a total of 23.4 billion yuan.
Price subsidies coupled with strict control of environmental protection, promote the province of large-scale coal-fired power plants, clean production. By the end of last year, Jiangsu Province, a total of 225 sets of 73.6 million kilowatts coal units to complete the environmental transformation. Combined with the transformation of coal to the end of last year, out of sync, Jiangsu Province, small thermal power units 2.95 million kilowatts.
Coal transformation of wide coverage, high standards, emissions dropped significantly. Emissions of coal dust, sulfur dioxide and nitrogen oxides three major pollutants, Jiangsu line monitoring mean values of 2.3 mg / cubic meter, 18.5 mg / cubic meter and 35.5 mg / cubic meter, effective domestic optimal. Transformation, Jiangsu Province, to proceed with flue gas heat recovery, central heating, shutting down small thermal power, 25.7 million tons of standard coal last year to save.
Significantly reduce the amount of coal emissions at the same time, the province "Blue Sky index" every year. According to the Provincial Department of environment statistics, since 2013, the province PM2.5年均浓度连续 six years continued to decline, good days than from 60.3% in 2013, rising to 68% last year.
