gas heating industrial water tube hot water boiler machine

Henan differs from coal-fired boilers and boiler gas at 1, circulating fluidized bed combustion boiler is fired by a coal crusher, by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; by circulating ash heated, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2, mainly by the combustion products of coal ash and water and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from the flue gas into the atmosphere, polluting the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions from coal-fired boilers Henan relative gas boiler, SO3, NOx is much less. 3, the general ventilation negative pressure combustion coal-fired boiler, a combustion process with the base by the induced draft fan and the blower mating fit together to complete coal combustion process, requires a lot of air and the furnace wall due to the leakage of flue excess air ratio of up to between 2.1-2.5. Henan micro gas boiler combustion positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion flue and the furnace wall, the flue outlet air ratio operation may 1.05-1.2.4, boiler control due to coal fired boiler, material thickness, amount of the blowing, the amount of the wind, oxy-acetylene ratio and other reasons, to be difficult to automatically adjust the boiler operating parameters according to the load. The Henan factors less impact on gas boiler, the burner may be adjusted according to the size of the load valve, easy to achieve automatic control.

August 10, 2018, Shanghai Industrial Boiler Research Institute Co., Ltd. (hereinafter referred to as the working pot), the National Boiler and Pressure Vessel Standardization Technical Committee of Professional Committee of boiler energy conservation (hereinafter referred to as the Commission) was held in Chengdu, organizational GB / T16508 "shell boilers" revision of the second meeting of the reported revision of the second meeting, the main author of this standard, pot capacity standard Committee appointed sub-standard boiler, the special committee secretariat a total of 10 experts attended the meeting.

Organized by the Shanghai Institute of Industrial Boiler Co., Ltd. Deputy General Manager, committee chairman Wang Shanwu chair. He said the main author of the unit where the standard of support GB / T16508 standard revision of thanks and hope the standard revision process experts complement each other, support each other, the GB / T16508 benchmark revision as the boiler industry standardization work seriously treat, carefully modified. Amended in accordance with the basic principles of the first meeting to determine, in addition to technical support for the "Boiler Safety Technology Supervision" (referred to as "Boiler Rules"), but also take into account the needs of industrial boiler manufacturing enterprises, between consideration and GB / T16507 harmonization. At the same time listen to opinions, to further enrich the standard revision work force, give full play to industry leading products representative firm.

Yung pot boiler Technical Committee Standards Committee Secretary-General Zhang Rui introduced GB / T16507.1 "The first part of the water-tube boilers: General" and GB / T16507.2 "The second part of the water-tube boilers: material" revised draft of the general framework and main content.

Money Fenghua special committee Secretary-General reported on the GB / T16508 since revised "shell boilers" start, the main author of each criterion according to the revised terms of reference and requirements, the completion of the GB / T16508-2013 "shell boilers" since the implementation of the views of summary each sub-standard and contrast "boiler rules" (issued), the sub-standard job descriptions revised terms.

GB / T16508 the sub-standard main author of this according to the relevant sub-standard content and "Boiler Rules" (draft for approval) comparing the results of the relevant sub-standard and harmonized need to modify the content of the standard version 13 implementation of the existing problems and proposed amendments analyze and explain proposed amendments focus on the sub-standard and major amendments envisaged.

Experts on key issues related to the sub-standard for the exchange and discussion to reach a consensus on major revisions of this standard and requirements.

Meeting according to GB / T16508 revision schedule requirements, arranged next phase of work, the following:

1. Revision of Standards fleshed out power to complete the Standards Working Group set up before the end of August;

2. Please carefully review the main author of each standard GB / T16508.1 ~ 16508.8 major amendments description, and recommend changes, submitted to the Shanghai International Industry pot special committee secretariat by August 25;

3.GB/T16508 the sub-standard main author collected the views, modify the preparation of the draft (draft) on the basis of the draft text, submitted to the Shanghai International Industry pot special committee secretariat on September 30.

Steam boilers What is the function? Too many in the form of steam boilers, would like to give a quick four tons of ordinary steam boiler talk. Water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Let me say a boiler pot. This boiler is a boiler drum with a water cooling wall at about the subregional arrangements drum pyrotechnic two return pipe, before the folded portion of the drum front smoke box. Between the drum and the tank in connection with the downcomer tubes and water-cooled bi, constituting the frame of the combustion chamber. There upper steam separator drum to reduce the water vapor out of the tape. Pan heating surface of a lower portion of the drum, and the water cooling pipe bi pyrotechnic tube. A chain grate combustion section and drive means, coupled with the combustion chamber pan rack on the frame configuration composed of the grate. Four weeks envelope refractories. . From coal fired into the hopper, the shutter coal front portion while sealing air control seam thickness. Blast into the lower part of the combustion chamber is a place that boiler greater resistance, need to force the blast. Cinder burn out, through the grate in the rear portion of the olecranon iron discharged from the machine to send out of the furnace slag. The boiler flue gas from the rear, by the front drum smoke tube a return line, the return from the two rear return smoke tube, and then into the dust separating ashes, and then discharged through the chimney draft fan. Not only is the induced draft fan exhaust fumes, the negative pressure of the boiler operation is required. Steam boiler pressure vessels, safety devices is necessary. Boiler necessary water level gauge, pressure gauge, safety valve, thermometer, and under the pressure of the electric pump can pay, and the vapor pump when power is off can also be used. Boiler water must be softened, as well as water treatment equipment.

WNS0.7-1.0 / 115/70-YQ: Horizontal representative of the internal combustion type gas heating industrial water tube hot water boiler machine, rated thermal power 0.7MW, Rated water pressure 1.0MPa, rated export / import water temperature 70 degrees Celsius and 115, respectively, fuel oil or gas. 1, rated thermal power: refers to the heat input per unit of time, common units kW kW or MW MW. There are some people to represent the output size of the hot water boiler tons.
