ce approved anthracite coal steam boiler

Works ce approved anthracite coal steam boiler because the steam boilers and conventional boilers are not the same, because it does not require annual inspection, so there are a lot of users recently asked my principles steam boiler, steam boiler is how it works, I will give you an analysis by the steam today working principles of steam boilers in steam systems, water heating in the heater to a predetermined temperature, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the downcomer inlet waterwall header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam flows to the steam drum by the upper superheater, continues to be endothermic superheated steam of 450 deg.] C, and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere. That's all steam boiler works with you about today, the company's steam boiler 0.5 tons 0.5 tons horizontal and vertical steam boiler fuel gas-free acceptance, there is a need to contact us.

Problematic fired boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.

Recently, Xuzhou City ushered in the good weather blue sky, sweetness and light, a set of numbers from the Xuzhou municipal environmental protection department made us confident to bring back the blue sky. According to the latest air quality in the province informed that this year, two good days in Xuzhou City 73 days, an increase over last year eight days; PM2.5 concentration of 78μg / m³, the concentration of upward momentum have been effectively curbed.

"Coal-burning pollution" key problem is the political commissar of the governance of Xuzhou City, after the operation began, to more than 10 tons of steam coal-fired boilers implementation of classification regulation, the city's 18 coal-fired thermal power companies implement flue gas treatment project off white, investigate and shut down downtown bulk coal processing operations point 171, for 22 coal-fired power companies and the city's 11 coal production (including coal washing) enterprises in high frequency sampling.

Furniture, printing and dyeing, filling stations and other industries, focusing on pollution VOCs special inspection work, check the company focused on source control, process management, end of treatment, the treatment facilities to ensure the normal operation of equipment, environmental protection do not have the processing power of enterprise firm shall be eliminated by shutting down.

Rubber can be seen everywhere in life. There are more and more rubber products in the industrial sector. There are many varieties and wide applications. The main products are tapes, hoses, gaskets, rubber rollers, rubber sheets and rubber linings. Labor protection products. For rubber plants, boilers are a very important configuration. Rubber companies use steam generated by steam boilers. The rubber article can be vulcanized by a vulcanization apparatus to change the rubber article into an elastomer. Customers should choose the right boiler according to their own needs.
