expansion of gas boiler panel

National Day holiday just ended, Shenyang Environmental Protection Bureau threw himself into the urban environment construction. Before the onset of winter, the Shenyang municipal government will strictly control the air pollution problem. It is reported that Shenyang Environmental Protection Bureau issued out since November 1, Shenyang will strictly enforce the standards of air pollutants emission limits in particular, all the environmental standards of heating enterprises will be cleared out of the heating market.

Shenyang Environmental Protection Bureau issued "on the thermal power industry, coal-fired boilers execution of air pollutants in particular emission limits of the notice" in the next year (the "Notice") requires: Thermal power within the gamut of Shenyang, iron and steel, petrochemical industry and fuel emissions of air pollutants in coal boiler project "thirteen five" period should implement special emission limit standards.

Shenyang is also a good environmental citizen blue sky, Shenyang City this winter and will continue to adhere to "turn point furnace, load shifting blocked arteries," the implementation of standards. After heating units gradually open blocked arteries, Municipal Environmental Protection Bureau will strengthen the routine inspection of law enforcement, and pay close attention to on-line monitoring data 474 coal-fired boilers, boiler emissions of non-compliance immediately ordered to carry out rectification, and severely dealt with strictly waste-water treatment, ultra row of such acts. At the same time, the Shenyang municipal government will also heating units regularly conduct random sampling of coal quality.

It is understood, Shenyang open blocked arteries in succession since October 26 from heating. To ensure that excessive heat stable and safe operation standards, Shenyang will be fully commissioning of heating facilities, to solve problems in a timely manner to ensure the November 1 time blocked arteries heating, the temperature reaches above 18 ℃. After the blocked arteries, Shenyang will strictly implement the winter heating emergency plans to complete the repair within 6 hours general accident, complete repairs within 24 hours more accidents.

Shenyang Environmental Protection Bureau official says, the environmental protection department will be heating business day on-line monitoring, and strictly control their emissions of air pollutants. Over the years, Shenyang has been doing the heating business "remove small and large," the relevant measures, so that some can not afford to increase environmental protection facilities of small companies to large companies merge powerful, let Shenyang municipal heating more environmentally friendly. Strict implementation of the special emission limits of air pollutants standards, both national policy, but also the heating of corporate responsibility, companies must increase investment in environmental protection to ensure the discharge standards.

It is understood that this year, the Shenyang municipal heating will continue to increase the proportion of clean energy, clean coal existing store 230,000 tons, an increase of 30,000 tons last year. Shenyang City, natural gas and other clean energy heating an area of ​​150 million square meters, clean heating the proportion reached 45%, up 6% over last year. Reduction of 1 million tons of total coal year, 5000 tons of coal-fired boilers to complete denitrification, the city starting from November 1 particularly strict implementation of air pollutants emission limits.

WNS is a wet potshell three horizontal fire tube expansion of boiler panel return, this structure has three returns, the oil or gas well atomizer air mixed with the combustor, the combustion in the furnace corrugations, into the first chamber after smoke return pipe, a second front steering return pipe smoke box, smoke box after the last to, through the chimney. It different fuel has a strong adaptability, it can burn heavy oil, light oil, natural gas and city gas. Boiler type low cost, high efficiency, security and stability, space-saving, fuel-efficient, low-cost investment to buy fuel; all pull side butt welds, boiler safety, long life, low maintenance costs. Recovery tail with flue gas condensation, can effectively control the flue gas temperature, high thermal efficiency of the boiler. Quick installation structure, the overall performance of the boiler on the basis of high strength steel design, easy installation and transportation, saving space in the boiler room area.

Some of the causes direct impact on the thermal efficiency of horizontal steam expansion of boiler panel of the country are carrying out a blaze of glory roaring coal to natural gas operations, the choice of horizontal steam boiler, greatly reducing the fine dust contaminated with dust, along with toxic gases such as nitrogen oxides emissions It has also been suppressed. Thermal efficiency is a key measure of horizontal steam boiler, a good start and that is that let you look at some of the causes direct impact on the thermal efficiency of horizontal steam boiler. Through research departments, the heat loss of horizontal steam boiler is very important from two aspects: the combustion air-fuel ratio is not satisfactory and Smoke and heat loss. Smoke and heat loss reduction should be modified in the tail horizontal steam boiler soot waste heat recycling install, or choose would be more leading series condensing boilers. Combustion air-fuel ratio over the substandard Analysis: common horizontal ejector-type steam boiler burner choice, without the formation of air-fuel ratio can be flexibly adjusted. Most of the horizontal steam boiler selected non-automatic strong emission burner, leading to the root causes of unsatisfactory air-fuel ratio has the following areas: air-fuel ratio is not ideal is more important is divided into two kinds of probability: When an excess of oxygen, there will be endless excessive cold air is heat conduction, resulting in increased energy consumption horizontal steam boilers, hot horizontal steam boiler efficiency decreased; when oxygen is not standard, incomplete combustion occurs, generating heat horizontal steam boiler efficiency decreased.

When the 40 tons SZS series gas and oil fired expansion of boiler panel is running, the fuel enters the burner from the external air source, and automatically generates a high temperature flame through the automatic adjustment and automatic ignition function. The front end of the furnace enters the convection heating surface on the upper side of the burnout chamber, and then enters through the upper part of the front smoke box. the second part. The convection heating surface exits the boiler from the rear of the rear smoke box and is vented to the atmosphere. The saturated steam is generated by heating, and the working fluid is output from the main steam valve to the operating system.
