Therefore, regular cleaning gas horizontal return tubular boiler structures, boiler give bring a certain degree of security. Third, reduce resource waste gas boiler cleaning has obvious environmental qualities, at this stage of use coverage is very broad. We found that, once the clean-up work is not in place, resulting in the boiler thermal effects will greatly reduce the accumulation of scale. Under this situation in order to ensure adequate heating capacity then only continue to raise the temperature of the fire, which is increase fuel consumption resulting in a waste of resources.

In order to improve ambient air quality in the region, Linfen City, Shanxi Province with the actual situation, issued a notice "Linfen City in 2019 iron and steel, coking industry depth reduction plan". "Program" is mentioned, requiring all enterprises in the implementation of the transformation process of governance, compliance with the target, select advanced, mature, stable, and reliable control technology implementation of the transformation.

1, the end of June 2019, to complete the iron making and steel making ultra-low emissions transformation; the end of October 2019, the completion of the sintering head (pellet sintering) transformation of the ultra-low emissions.

Acceptance criteria: sintering (pellet) smoke particulate matter, sulfur dioxide, nitrogen oxide emissions in the reference oxygen concentration of not higher than 16% under the conditions (18%) of 10mg /, 35mg /, 50mg / m3; iron, other processes steelmaking emissions of particulate matter, sulfur dioxide, nitrogen oxides emission concentration is not higher than a standard 10mg / m3,50mg / m3,200mg / m3 of.

2, before the end of October 2019, the city's iron and steel enterprises to fully complete management and monitoring of fugitive emissions, fugitive emissions control, control, governance intelligent integration platform built

Acceptance criteria: transformation, steel companies outside the main source of fugitive emissions at 1 m, the particle concentration is less than 5mg / m3; the concentration of particulate matter emissions by organized collection after treatment is less than 10mg / m3.

3, the end of June 2019, to complete the coke pushing, coke ultra-low emissions of other transformation step; the end of October 2019, to complete the transformation of ultra-low emissions oven chimney.

Acceptance criteria: coke chimney particulate matter, sulfur dioxide, nitrogen oxide emissions in the reference oxygen concentration of not higher than 10mg / m3,30mg / m3,130mg / m3 under the conditions of 8%; coke oven coal, coke pushing step particulate matter emission is not higher than a standard concentration of 10mg / m3 of.

4, before the end of October 2019, the city's coking enterprises fully completed fugitive emission control and monitoring, fugitive emissions control, control, governance intelligent integration platform.

Acceptance criteria: transformation, mainly coking fugitive emission sources outside 1 m, the particle concentration is less than 5mg / m3; the concentration of particulate matter emissions by organized collection after treatment is less than 10mg / m3.

Fast horizontal return tubular boiler structure pressure receiving member is designed and manufactured in strict accordance with the specifications, to ensure the safe use of the boiler.

Liupanshui former gas steam horizontal return tubular boiler structure installation to handle documents installed gas steam boiler, should write "boiler installation started application form", and was carrying no less than the following materials to the gas boiler steam boiler for all earthly authority for examination and approval procedures for installation, approval after the order for construction: ① gas steam boiler installed original license; ② gas steam boiler installation boiler installation boiler room started the application form and engineering solutions; ③ gas steam boiler factory technical information; ④ steam boiler room floor plan and steam boiler room design information; ⑤ practitioner certificate installation companies involved in the job of workers. Former gas steam boiler installation, and installation company should also carry complete the ratification of the "boiler installation started application form" to the quality control unit for all territories gas steam boiler and pressure vessel inspection unit signed "Boiler Installation Quality Supervision, Inspection engagement letter" by the test unit values ​​for gas steam boiler installation requirements of supervision.
