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 boilers 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.

Steam boiler three indicators and characteristics of magnetic drive fast boiler company Henan ready before the start of a centrifugal pump with small series to introduce steam boiler three indicators and characteristics of magnetic drive centrifugal pump Before you start to express the characteristics of the steam boiler, usually steam boiler capacity, parameters, characteristics such as reliability and economy indicators. In this example and several characteristic index defined steam boiler: 1, evaporation and steam boiler heating power: the size of the steam boiler capacity is typically rated represented evaporation. Rated evaporation refers rated parameters (pressure, temperature), under the conditions of burning design of the fuel and to ensure that the design efficiency, continuous operation should achieve maximum evaporation amount (per unit time steam production), should this be the rated output or evaporation plate, by the symbol "D" indicates the unit is t / h or kg / s. steam boiler plant and may also be supporting the thermal power turbogenerator, i.e. kw or mw represented. From the viewpoint of energy conversion of view, the ability to heat a steam boiler with a rated heat input, i.e., rated thermal power is represented by the symbol "Q", the unit is kw.Q = D (iq-igs) = D △ i, formula iq for export steam specific enthalpy (kj / kg); ig of feed water specific enthalpy (kj / kg) to different steam, water evaporation parameters is compared or additive, may be the actual steam evaporation D terms. "standard evaporated vapor amount" Dbz ", producing a predetermined amount of heat absorbed per 1kg no standard steam is 2680kg, so Dbz = D * △ i / 2680t / h or kg / s. and the hot water boiler are denoted by thermal rating the size of the boiler capacity, the symbol "Q", in units of MW, Q = G (is - ih) × 10 ?, where G is the amount of hot water boiler (kg / s), ihs, irs boiler out saliva enthalpy (kj / kg) .2, steam or hot water: parameter steam boiler steam production means at the outlet of the rated boiler steam pressure (gauge pressure) and a temperature of the boiler producing saturated steam, generally designated vapor pressure, by the symbol "P", in units of MPa, for the production of superheated steam boilers or hot water, and the need to indicate pressure steam or hot water temperature, the temperature to whom Economizer fingering water temperature, meaning that when the drum into the boiler without economizer temperature water temperature indicated by the symbol "t", the unit is ° C. Preparation ① Check magnetic drive centrifugal pump start before magnetic drive centrifugal pump connection bolts and anchor bolt without loosening .② pipe connection inspection is appropriate, whether the center of the pump and driver in processing temperature, cryogenic liquid pumps, pipe expansion, contraction may cause axial disorders, bite, etc. Therefore, the flexible pipe joint requires the use of direct coupling and centering etc. ③ small, when stopped, no major changes in the centering of the pump and the motor room temperature magnetic pump: while large, high temperature magnetic pump run and stop in very different axis, for the correct centering generally require warming to operating temperature after running or stopping the pump, to ensure rapid re-centering of the axis of both rotor consistency to avoid vibration and pumps the cleaning nip .④ piping must be first cleaned of foreign matter before running pipe, welding slag, Never push objects off the pump body human. gauge mounted on the screen before and after inhalation tube, in order to monitor the operation of filtration The blockage .⑤ disk drive. Before starting remove the coupling, rotation of the rotor by hand if there is abnormal, and the motor alone test, check if it is consistent with the rotational direction of the pump. Joint rotated by hand, can be found in between the pump impeller and the casing without foreign body, the disk drive should be uniform weight, no noise in the pump.

ZBG further stated, "This Advanced Bio CFB -- or ABC -- is the largest and most advanced biomass CFB small steam generator for sale ZBG has ever supplied. Our goal for this project was to provide GDF Suez with a reliable, biomass-flexible boiler that would allow the client to build a high-efficiency green power plant - and we have achieved that objective."

The steam generated by the boiler is generally measured in tonnage, but the steam turbine power generation is calculated by heat, and the two can be converted: generator electric power MW = boiler tonnage × steam per ton × steam turbine efficiency × generator efficiency. The steam enthalpy depends on the parameters of the steam. The pressure and temperature of the steam are different, and the enthalpy value is also different. It is generally considered to be 0.7. The coefficient of steam turbine efficiency and generator efficiency depends on the power station unit system.
