Low nitrogen gas boiler market is mostly higher than the average prices of some gas boilers, then, we must first thoroughly understand where the difference between the two is what pushed up the price of low nitrogen gas boiler.

Furnace explosion of the causes of ordinary gas boiler steam boiler gas burned in open flame and furnace process, if the following three conditions appear, it is easy to attack blast furnace accident. 1, open burning furnace, furnace residual gas content limit to reach the fire. 2, open incinerator, several points Eventually, the content of the furnace gas reaches the ignition limit, and then incinerated. 3, halfway flameout, fuel discharge series, spontaneous combustion of the fuel in the furnace temperature can change, so that the gas reaches the ignition limit of the content, and then incinerated. Forming flame halfway reasons are as follows: 1, gas is not supplied in succession. 2, during the adjustment, the valve opening degree increases or decreases suddenly. 3, lean fuel-rich flammability limit narrow. In order to avoid the onset of blasting incidents of burning fuel gas-fired boiler initiative and flame monitoring protection devices should be installed.

Works wns gas steam boiler and basic structure wns applications than gas hot water gas boiler steam boiler lot of wide, including food plants, chemical plants, building materials plants, steel mills, etc., whether light or heavy, are inseparable from today take a closer look at the principles of steam boiler and steam boiler structure wns gas. 1, the working principle of gas steam boiler wns: WNS gas steam boiler furnace combustion heat of the fuel released, the water evaporated in the boiler is heated into steam. Water pan (drum) released by combustion of a gaseous fuel energy continuous heating furnace, the temperature rise and generating pressurized steam. When the boiling point of water increases as the pressure is raised, the pan is sealed. Expansion of the steam boiler is restricted, a pressure forming a thermal power (strictly speaking, the steam boiler is heated by a constant voltage to the saturation of water in the boiler water tube formation), is a widely used energy. 2, wns gas steam boiler basic structure: WNS gas boiler steam boiler consists of two main housing and the furnace and accessories, instrument accessories, automatic control and protection system components, which ensure continuous safe operation. This boiler is for a water boiler, is provided with two left and right sides of the tube back to the combustion boiler smoke tube, before the cigarette before the boiler body is reentrant. There downcomer and the bottom of the cooling pipe is connected between the drum and the box structure constituting the combustion chamber. Separator drum, in order to reduce the water vapor. Boiler tube boiler heating surface is a lower, water-cooled tubes and pyrotechnic tube.

It is understood, Shaanxi Province, 2018 - Continuing to promote the 2019 inspection work in key areas of defense sky war, now in its third phase. November 22, according to the requirements of the program of work for the inspection team to carry out all the Guanzhong area of ​​Shaanxi Province counties (cities, districts) inspection work, inspected 262 units, identify problems and 49, have been transferred to the supervision of Shaanxi Province 20 .

20 environmental issues in the supervision, accounting for 8 in Xi'an, Weinan City, accounting for 7, Baoji City accounted for two, accounting for two Xianyang City, a Korean city of Tongchuan City, Yangling Demonstration Zone and the New West Ham is not problem found.

More units found the problem, companies of "scattered dirt," the one, accounting for 5%; industrial pollution prevention and control 10, accounting for 50%; a coal-fired boiler renovation, accounting for 5%; comprehensive management of dust 1 , accounting for 5%; complaints 4, accounting for 20%; at three open burning control, accounting for 15%.
