10 best boilers of 2019
stop the 10 best boilers of 2019 to dry it :
2 hours before the boiler stoped,with the help of water supplying system and medicament system, the fireman add ammonia to the boiler to increase the PH value and ammonia concentration. In this way, a protection membrane will be formed in the boiler with which the corrosion caused by the boiler water will reduce during the idle time.
Supply shortage, how to deal with lack of gas 10 best boilers of 2019 gas processing method 1 correctly, with quick access to the natural gas dispatch Contact ask the cause of the accident clean, and take feasible measures; 2, report to the higher authorities and leaders; 3, always observe the combustion, wheat yellow flame is normal.
The main task of monitoring and adjusting Henan gas 10 best boilers of 2019 running Henan gas boiler means to monitor and adjust the operation of its main tasks are: 1. Maintain evaporation within the rating of the boiler, the steam quantity to meet user requirements, avoid overload operation; 2. maintain normal pressure and temperature; 3 balanced water, and maintain the normal water level in the boiler; 4 to maintain steam quality compliance; 5. maintaining good combustion, improve boiler thermal efficiency, and comply with environmental requirements; 6 . ensure the safe operation of the boiler unit. Henan run gas boiler means that the working conditions at the time of boiler operation, it is through a series of operating parameters to reflect. These parameters are referred to as operating parameters, such as vapor pressure, evaporation, evaporation temperature, drum level; flue gas, air, water temperature and pressure; the fuel consumption and smoke components. The main factors Henan gas boiler operating conditions are: the boiler load, and fuel, feed water temperature, excess air coefficient. Boiler normal operation, it must control the water level, pressure, temperature within a certain range to suit the user's own safety and thermal boiler equipment requirements. Excess air ratio influence Henan gas boiler operating conditions for relatively large. Excess air ratio is increased, mainly due to air leakage. The increased excess air, the furnace temperature is lowered, reducing the radiation heat transfer, the convective heat transfer increases, also increases the amount of smoke, heat losses increase, reducing the thermal efficiency of the boiler. At the same time, induced draft fan or blower power consumption increases. Excess air coefficient is determined by each site smoke constituents determined. The efficiency of a combustion analyzer may measure the contents of carbon monoxide in the flue gas, it is determined whether the combustion sufficient to direct fuel ratio adjustment.
Lanzhou City, Gansu Province, the transformation of coal-fired 10 best boilers of 2019 control policy in accordance with the latest introduction of the "not big on the small" principle to give "Yijiangdaibu" financial support to owners of units, specific subsidies are as follows:
1, for a single 1 ton / hour or more than 0.7 megawatts of clean energy and coal-fired boilers by 100,000 yuan to subsidize steam tons of standard /.
2, coal-fired heating boilers mentioned standard governance and meet the national air pollutant emission limits in particular boiler, according to subsidize 50,000 yuan / ton steam standards, subsidies does not exceed 30% of the total investment quota.
3, for a single 1 ton / hour or 0.7 megawatts of utility units (including schools, health centers, hospitals, neighborhood or township government offices and other public units) clean energy transformation of coal-fired heating boilers in accordance with the actual heating area subsidies, allowances of 100 yuan / square meter.
