Recently, the Guangzhou City issued an action "Guangzhou 2018 annual work plan for comprehensive prevention and control of air pollution," the bureau of law enforcement to monitor the detachment on August 28 = 29 organizations launched a special enforcement action against a biomass combined water tube boiler dealer.

The special enforcement action by the municipal and district levels of environmental protection departments jointly launched, deployed Yuexiu, Tianhe, Haizhu, Huangpu, Conghua five district environmental protection law enforcement backbone, with the Guangzhou City Environmental Protection law enforcement inspection detachment composed of 18 cross-law enforcement group, to increase the city all registration to carry out quality checks of 125 biomass boilers in the book, focus on examination of Guangzhou boiler emissions monitoring system in Zengcheng District registered the existence of complex biomass boilers coal or other high-polluting fuels, whether there are special furnace and supporting bag dust removal facilities, whether the normal operation of the boiler control facilities, whether discharge standards as required entry and update Guangzhou boiler emission monitoring system and other issues.

After verification, the registration system by the city list in the boiler has been disabled (off or relocated) boiler station 43, not included in the other eight found regulatory list table 133 actually inspected. Among them, 28 units involving suspected violations accounted for in the boiler problem with the boiler (90 units) ratio of 31%, the problem of coal-fired boilers in complex 2, the resurgence of firewood, 11, allegedly did not apply for environmental protection procedures, waste gas treatment is not installed facility or facilities are not the normal use and other illegal activities 15. For complex high-polluting coal and wood fuel boiler according to law-site seizure and transfer penalties and territorial environmental protection departments to follow up treatment in accordance with the relevant provisions of Article 107 of the "People's Republic of China Air Pollution Prevention Law." The rest were arrested for illegal transfer of territorial environmental protection departments for investigation.

20 tph SZS gas-fired water tube combined water tube boiler dealer project for chemical industrySteam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. Tsaker Chemical Group Limited, listed in Hong Kong Stock Exchange, has four business units including dyestuff BU, pigments intermediates BU, battery materials BU and environmental protection BU. Dye intermediates BU, located in Dongguang County, Cangzhou City, Hebei Province, and mainly engages in the production and sale of dye intermediates DSD acid, NTS and dinitrotoluene sulfonate (DNTS). Dye intermediates BU (hereafter referred to as BU) planned to introduce natural gas boilers to response to increasingly stringent environmental protection policies like “coal-to-gas”. Because the environmental protection boilers on the market vary in quality, the BU took enormous care in choosing the boiler supplier. After several comparative studies and cost analyses, the BU was deeply impressed by the excellent products and services from ZOZEN, and ultimately achieved cooperation with ZOZEN. ZOZEN provided them with SZS gas-fired steam boilers after on-the-spot investigation. This kind of gas-fired boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to30mg/Nm³.

Requirements of steam combined water tube boiler dealers and steam boilers relatively broad range of applications in the food processing industry, its main principle is the use of steam to power. Steam boilers sold There are many different types of consumers do not know if steam boiler, it will be more difficult to select them on the market. Steam boiler is for people to provide quality steam main machine, give humanity a great change in before the advent of steam, the emergence of the age of steam introduced into the era of modern human civilization. And now there is a steam boiler once again proved that human potential is unlimited, it appears to help people is enormous. Large steam boilers Limited supply plays in people's lives the role, is like bathing, eating, industry, etc., it can be said to require the use of steam places need to use steam boilers, steam boilers, after all, is to provide the main tool of steam. Industrial production in steam boilers provide steam for people at the same time to the production of human powered, so that people become more convenient in production. In life steam boiler to provide steam that can help people create high-quality food, and why that is because we were able to take a shower steam boiler in the cold winter. These are the steam boiler to help us. Steam boilers are cyclical, do not always use, as if used for heating. North weather is very cold, winter will begin once inside steam boilers to provide heating, but over the winter is basically a steam boiler that is placed there is no need. This is also the time when the steam boiler most prone to failure, so off time maintenance work is very important. Steam boiler before the fire, check valves to pipes, steam pipes, water gauge, pressure gauge, relief valve and the discharge valve or the like, whether it is intact, can be used normally. Steam boiler water, first softening treatment and water quality to clean, can not have impurities. The water gauge glass, which outer shield should be sturdy, and to clean. How the operation of the water table, if an exception should be handled immediately one should always observe. Safety valve and can not be adjusted in order to avoid problems. If the gauge reaches allowable working pressure of more than 80%, then one should be allowed to exhaust valve, in order to avoid excessive pressure.

4, furnace maintenance methods

In order to make the boiler safe and economic operation lasting, must in daily use, strengthen the maintenance of the boiler, which is to prevent the lower thermal efficiency, an important measure to avoid the use of state of deterioration and boiler accident.
