January 16, Harbin Municipal Environmental Protection Bureau Director of the atmosphere and noise pollution control at the public hall, Li Bin, said: "Harbin problem-oriented, focused on solving the coal pollution environmental air quality, autumn and winter of straw burning pollution." By a wide range of governance, 2018, Harbin has made in terms of ambient air quality improvement remarkable results, the standard number of days 310 days, an increase of 40 days, for the introduction of new environmental quality standards since the best of the year.
Prior to 2017, the total removal of Harbin urban built-up area of small boilers range of nearly 3,000. 2017, Harbin started the largest in the history of the elimination of small-scale boilers battle, tear down 9 district built-up areas and industrial parks within a small boiler 2074 units. 2018, further expanded the phase-out range, expanded from 9 Zone has outside built-up areas, where the built-up area in District 9 out of 10 tons of steam per hour of coal-fired boilers to achieve foundation "clear" on the hour and eliminated more than 10 tons of steam coal-fired boilers 99 units, out of the city a total of 1191 units. The results accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants.
According to reports, in the fall and winter seasons, Harbin straw Jinshao pay close attention to the work to implement the five grids responsibility, building straw Jinshao 24-hour duty system inspections, inspection teams at all levels of uninterrupted inspection. In addition, Harbin has also implemented emission standards of air pollutants, vehicle control, open-air barbecue ban, dust management, especially in heavy weather pollution contingency timely warning, take active control measures played a role in the down-clipping. Through various management, air quality has been greatly improved.
Rice husk fired moving grate type biomass fired steam boiler is a kind of biomass fired steam boiler which uses rice husk or straw as its fuel. Mostly using rice husk as fuel, it is economical and eco-friendly. Rice husk biomass fired steam boiler adopts membrane water wall structure to improve heat transferring efficiency. And its arch adopts water cool structure to make sure the rigidity and the reliability of the arch. Besides, energy-saving rice husk fired steam boiler can also burn wood pellets, chips, bagasse, palm shell and other solid biomass energy.
Vertical pressure moving grate type biomass fired steam boiler component damage cause an explosion in the explosion normal working pressure: the pressure receiving member defective or damaged vertical steam boiler, and gradually developed to a certain extent. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. The erosion of the steel sheet, equipment for manufacturing and testing of weld defects, vertical steam boiler accumulation of dirt poor heat transfer, rapid cooling apparatus taking water caused when vertical steam boiler water. Combustion furnace explosion: mainly vertical steam boiler explosion instantaneous deflagration of combustible gases in the furnace and the liquid concentration reaches a certain limit. Explosion in the furnace depends on the concentration and the heated mixed gas premise. Vertical steam boiler furnace if not cleared before starting or ignition failure is not required to operate, blind firing, furnace explosion is likely to occur. Operating pressure exceeds the design pressure: vertical steam boiler pressure gauge failure, the safety valve does not work after overpressure, boiler workers from work, supervision is not enough, the main steam valve is closed, the relief valve malfunction. Vertical steam boiler design is unreasonable, different manufacturing quality, the material does not meet the requirements, poor weld quality, maintenance is not timely, long downtime, resulting in corrosion vertical steam boiler, reducing the carrying capacity of the steam boiler explosion caused by overpressure.
Boiler structure and function of which types of the more popular types of biomass boilers is a boiler to biomass energy as a boiler fuel called biomass boilers, moving grate type biomass fired steam boilers into biomass, biomass hot water boiler, biomass stove , biomass gas steam boiler, biomass boiler vertical, horizontal biomass boilers. Classification of biomass boilers: Horizontal biomass boilers, biomass boilers vertical. Biomass Gas Gas steam boiler, biomass steam boiler, biomass hot water boiler, steam biomass gas stove. Unitary structure biomass boilers boiler consists of two parts, safety and auxiliary equipment dosing device. Boiler furnace, drum, burner, water wall, superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler drum main functions: The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, fresh air ventilator tank Axial fan centrifugal fan avoid pot containing a high concentration of salt and impurities water with the steam entering the superheater and a steam turbine. Internal boiler drum apparatus: comprising a steam separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also for further separation louvers, steel wire or plate or the like are vapor . The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities.
