Gas-fired steam combi central heating boiler safe operation Tidbits gas steam boiler safe operation Tips 1. The operator should be familiar with the structure and principles of the furnace and the production of basic requirements for thermal equipment, and constantly sum up experience in practice, control coal thickness, so that the full combustion reduce chimney smoke, protect the equipment in a safe, efficient operation. 2. The new oil furnace or restart long home, gas steam shall dehydration stage heating requirements. 3. export oil temperature should be set below 280 ℃, when the oil temperature exceeds 200 ℃, should pay more attention to temperature, oil temperature should slow down, only non-oil change and over-temperature operation. 4. close contact with production, timely and slow down the oil temperature, while meeting production requirements, taking oil lower, will help extend the life of gas and steam energy savings. The normal oil level: the lower tank oil level is low, high-high oil groove. This ensures that the emergency shutdown when cold oil replacement system and prevents air from entering the pipe. When the high slot in a low oil level should start to replenish gas steam injection pump. 6. The circulation pump is allowed outage in the operation of the burner, when the pump is failure or power outage, Fan stop, depending on oil temperature and take appropriate emergency measures: rapid opening valve 7, the cold head tank oil up through the furnace coils to the low tank. 8. Coal and wet coal hearth fire or discharge out of the furnace, non-water washed pouring furnace. These measures should be completed within 3 to 5 minutes, to prevent the high oil temperature coke deposits other accidents. 9. normal shutdown, the oil temperature should be reduced to below 100 ℃, stop the pump before. 10. When the outlet pressure differential below the set value, the induced draft fan should outage. Then there is a fault system, feedback should be immediately removed or, if necessary, should pressure fire outage. 11. fireman should stick to their posts, do a good job operating records and shift work, and regular inspection and maintenance equipment.

Hefei is the blue sky to win the Battle of key areas for innovation to create an international influence is of great significance. Is determined to win the battle of the blue sky, the city combined with the actual situation, formulate a three-year action plan to win the embodiment Battle of blue sky. Details are as follows.

I. Target: 2020, sulfur dioxide, total nitrogen oxide emissions were reduced over 23.1% in 2015, more than 24.2%; PM2.5 concentration decreased more than 18% in 2015, the ratio of the number of days air quality assessment requirements up to the national , severe pollution and over several days ratio decreased by more than 25% compared with 2015; the full realization of "thirteen five" binding targets.

Second, the continued implementation of the total coal consumption control. By 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's total coal consumption to complete the tasks assigned by the national and provincial; new coal projects to implement the reduction of coal instead.

The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement may be within the total national and provincial construction plan developed according to the control range, co-ordinate arrangements for the construction of ultra-low emission coal-fired capacity unit.

Third, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, ceramic, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry characteristics can actively promote industrial production, building heating and cooling, transportation, agricultural production, the implementation of the residents living in five major areas "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for. Of the new "coal to gas" projects, we should adhere to increase coal gas reduction to gas will change under the premise signed gas supply contracts, orderly implementation.

Fourth, to carry out comprehensive improvement of coal-fired boilers, coal-fired boilers to increase efforts to eliminate, consolidate the results of coal-fired boilers eliminated. Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation, one by one registration. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour and coal-fired boiler above (except boilers fired power plant) all meet special requirements emission limits; allowed to remain 65 tons of steam per hour coal-fired boiler and above all the complete energy transformation and ultra-low emissions within the city. County (city) district, zone one by one before the end of June 2019 to develop low-nitrogen combustion rehabilitation programs for existing gas boiler, complete combustion of low nitrogen transformation in this area of ​​existing gas boiler before the end of 2019 more than 50%, before the end of 2020 transformation is substantially complete; after transformation principle NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. Urban built-up area of ​​ultra-low emission biomass boilers implement reform.
