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.
In mid-November, Langfang City, Hebei Province continue to promote coal-fired boiler pollution problem, do the atmospheric release 2018 Fourth supervision order, supervision order states: the country, relevant departments directly under the city's control to quickly take a series of measures to prevent and strictly control burning coal boiler pollution problems.
Now is the time winter heating season, but also the critical period of the comprehensive management of air pollution in the autumn and winter season, the coal-fired heating boiler emissions standards are the focus of Langfang City, air pollution prevention and control. To ensure that coal-fired heating to achieve effective control, reduce emissions, minimize the adverse effects on air quality, atmospheric Langfang City Office will join together to focus, determined to win the battle in autumn and winter air pollution of coal-fired boilers.
Steering proposed order, the relevant departments to combine their job requirements for environmental protection, to develop a coal-fired boiler heating energy saving solutions for special work, establish special supervision and inspection mechanism for all heating stations in the main city within the city limits, supervision and guidance heat stand while ensuring a stable discharge standards, to protect people spend a warm winter. Various environmental protection departments will strengthen the tracking and monitoring of emissions of various heating stations, to be serious penalties for excessive emissions of coal-fired boilers, but also will continue to maintain compliance or below the City heating boilers requirements set emission standards for reward and subsidies .
The main purpose of the boiler is the main purpose of what the boiler: Boiler national economy is an important energy supply equipment. Electrical, mechanical, metallurgical, chemical, textile, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Boilers using fuel combustion energy released or other energy to the working fluid (heat carrier intermediate) is heated to a certain device parameters. For heating the water to make it into the boiler steam is known as steam boilers, also known as a large steam generator for heating water to make them more water into the boiler temperature, known as the hot water boiler for heating of Heat Transfer Fluid It called boiler organic heat carrier boiler.
As the cost of powering this equipment by burning fossil fuels has steadily risen, the use of biofuel co-generation as a source of power production has become more prevalent. Many sugar mills have updated their bagasse fired boilers and linked them to generators that produce electricity used to power the mill’s operations and to be sold to the local power grid.
