boiler for psc factory

The method of starting the boiler for psc factory during boiler startup control drum wall temperature difference of the process to be controlled in a predetermined drum wall temperature difference may take the following measures within 40 ℃: (1) water temperature before ignition can not be too high, not too fast speed, according to rules of execution. (2) water is completed, the bottom may be put into steam heating conditions. (3) strictly control the raising rate, in particular 0 ~ 0.981MPa boosting speed stage should be less than 0.014MPa / min. Rate of temperature rise not greater than 1.5 ~ 2 ℃ / min. (4) should be regularly switching angle oil gun, until the next row when four full cast oil gun, each part as far as possible evenly heated. (5) via the above-described operation can not effectively control the drum, the lower wall temperature, then when the approach or reach 40 ℃ booster should be suspended, and the sewage regularly, in order to enhance the circulating water, and stabilized until the temperature difference is less than 40 ℃ line boost.

Notes 1 boiler for psc factory installation, low temperature hot water floor radiant heating system has not been calibrated, non-operational use. 2, commissioning low temperature hot water floor radiant heating systems, it should be provided under conditions of normal heat and power. 3, the heating must first fill layer concrete curing period ends, and after the filling layer is completely dry. 4, debugging low temperature hot water floor radiant heating system should be carried out in the construction unit construction unit fit. 5, during the initial heating, hot water heating should be gentle, the water temperature should be controlled at higher than the ambient temperature was 10 ℃, and should not exceed 32 ℃. At this temperature, it should be run continuously 48h; 24h after every 3 ℃ elevated temperature, until the water temperature reaches the design. In respond to this temperature each fraction, a heating tube connected to the sump by way adjusted until normal operation. 6, the heating effect of low temperature hot water floor radiant heating systems, should be at the center of the room to 1.5m from the ground bulb thermometer indicating the temperature of the black, as the basis for the evaluation and assessment.

Recently, Taiyuan, Shanxi Province Environmental Protection Leading Group issued a circular on promoting the transformation of ultra-low emissions and low nitrogen transformation of biomass boiler for psc factorys gas-fired boiler. Resolutely implement - the latest requirements "2018 in Beijing, Tianjin and the surrounding areas in 2019 autumn and winter tackling air pollution comprehensive management action plan" in, and further reduces boiler emissions standards.

1, 2019 until October 31, the use of boiler tail decoration efficient dust removal, desulfurization, stock device is accomplished ultra-low emission biomass boilers transformation of the necessary funds by the counties (cities, districts) and users together to solve, not the municipal finance I grant.

2, October 31, 2019 update for ultra-low emissions of nitrogen gas boilers, electric boilers biomass boilers, municipal finance one-time grant 30 yuan / square meter construction costs, in part by the lack of counties (cities, districts) and user common solutions.

Way: by transformation to replace the low NOx combustion, a flue gas recirculation device installation mode, NOx emission is less than 30 mg / m item.

NOx emission cuts ≥50%, and the concentration value of less than 30 mg / cubic meter project, to give up prize money of 30% in accordance with the transformation of investment.

3, after December 31, 2017 the new gas boiler, should meet the emission requirements on Taiyuan low NOx combustion, but does not enjoy the low NOx combustion subsidies.

Feed Water & Steam Circuit – this section deals with supplying of steam generated from the boiler for psc factory to the turbines and to handle the outgoing steam from the turbine by cooling it to form water in the condenser so that it can be reused in the boiler plus making good any losses due to evaporation etc.
