Yesterday, the largest boiler in the Chengdu Ring Expressway completed the conversion of coal to gas. About one week after the project is commissioned, if the supply of natural gas is stable, coal-fired boilers will be suspended; two months of successful trial operation, coal-fired boilers will be completely abandoned, which means that the half-century chimney is expected to be dismantled after the Spring Festival. .
The coal-fired boiler company has a total of six coal-fired boilers. The steam produced by it mainly meets the requirements for surface treatment and process heating. The four 80-ton coal-fired boilers in use were built in the late 1970s. Severe aging of equipment, boiler thermal efficiency is only about 63%, a large energy waste. According to statistics, in 2013, these boilers emitted 106.0 tons of sulfur dioxide to the atmosphere, and 250.3 tons of dust was emitted, which had a significant impact on the surrounding environmental quality.
At the end of June 2013, during the investigation of the company, the leaders of the Chengdu Municipal Government proposed to start the coal-to-gas conversion project as soon as possible and end the history of burning coal in the high speed around the city. The difficulty in transformation is to ensure the stable supply of natural gas. In order to ensure that the production is not affected, the company finally decided to use a dual-purpose fuel gas fuel boiler. Once the gas supply is insufficient, it can use fuel to supplement.
The basic principle of the operation of the fuel gas boiler is to soften the fresh water first by the sodium ion softener, and then by the deaerator to remove oxygen, and the water quality meets the relevant standards for industrial boiler water quality. The treated demineralized water is sent to the steam boiler through a high-pressure pump. After the heating, the temperature of the steam generated by the boiler can reach 194°C, and then it is sent to the production area through a steam pipeline.
According to estimates, this transformation project can save 36,000 tons of water resources each year, save about 8,000 tons of standard coal, and save about 1.5 million degrees of electricity. At the same time, dust emissions were basically eliminated, and the emission of sulfur dioxide (SO2) dropped to 1.45 tons per year, 72 times less than before the reform.
