water tube waste heat steam recovery steam boiler

December 20, "Shanghai Air Pollution Prevention Act," a modified version of issued and published by the Shanghai Municipal People's Congress Standing Committee, with effect from January 1, 2019 came into effect.

First, the discharge of industrial waste gas or coal-fired heat production specified operating business units of toxic and hazardous air pollutants listed in the directory of institutions, central heating and other facilities to implement pollution permits management according to law shall, pursuant to the provisions of Shanghai, to the municipal or district environment department applied for and obtained the focus of air pollutants discharge Permit (hereinafter referred to as emission permits); no discharge permit shall not discharge the focus of air pollutants.

Emissions to air pollutants shall comply with the air pollutant emission standards, compliance with the total focus of air pollutant emission control requirements. New construction, expansion, renovation project focused on emissions of atmospheric pollutants, the focus should obtain the total air pollutant emission targets in accordance with the provisions of, and environmental protection examination and approval procedures for construction projects. Need to apply for a discharge permit construction projects shall obtain emission permits before being put into production as required.

Second, easy to appear in the autumn and winter of heavy pollution weather, the city of steel, building materials, coking, casting, aluminum, chemical high emission industries related company should arrange production plan to strengthen air pollution control measures. Economic information administrative departments should strengthen the guidance jointly with the municipal environment department.

Third, the environment department to determine the emissions of air pollutants key sewage units, must be configured using air pollutant emission-line monitoring equipment, and the environment departments into a unified monitoring network.

Fourth, in addition to coal-fired power plant, the city's ban on new or expanded coal burning, heavy oil, residual oil, petroleum coke, high-polluting fuel (hereinafter referred to as high-polluting fuels) facilities; the construction of coal-fired power plant in accordance with the relevant provisions of Shanghai .

Gas boiler module introduces gas boiler module composed of a plurality of modules boiler heating system, heat on demand. Module can make full use of the advantages, high thermal efficiency, energy saving effect is remarkable; work independently of each module, a single failure of the entire system does not affect the movement, without backup boiler. Advantages: quiet and efficient gas boiler module burner gas boiler module efficiency stainless steel grate combustion, forced burn, burn silent vibration-free, to ensure a quiet environment for a variety of installation site. Boiler 20mbar standards for municipal low pressure natural gas without building an independent regulator station, reducing pipeline investment, saving construction costs. Commercial Gas import module boiler safe, reliable, open-system installation module boiler water pressure during operation is always in addition to normal pressure, but also with multiple perfect safety functions: flameout protection; anti-dry protection; frost protection; water level is too low protection; auto exhaust protection; preventing overheating protection leakage protection; built-in installation: water system is always closed during operation under pressure 0.05 ~ 0.3Mpa, the system having a security function in addition to an open-mounted, but also with protection against: expansion pressure protection system; low-pressure water protection system, high-pressure safety relief protection.

Safety devices and type boilers pressure vessel, the pressure vessel safety apparatus is designed to pressure vessel means can be an attachment device mounted on the surface of the safe operation of the device, and often referred to as safety accessories. Boilers, pressure vessels a safety device, according to their performance or use can be divided into four types: 1, interlock means for preventing operation of the control mechanism provided by mistake, such as the interlock switch, interlock valve. 2, the alarm device refers to the device unsafe occurs resulting in the dangerous state during operation, it can automatically send an alarm sound or other obvious signals of instruments, such as pressure alarm, temperature monitor and the like. 3, the metering device can automatically display apparatus refers to the operation of appliances and security-related process parameters, such as pressure gauges, water level gauge, a thermometer and the like. 4, the device automatically when the discharge pressure of the overpressure relief device means, such as safety valves, rupture discs and the like.

Now in the boiler market, using a condensing gas boiler is more and more common, mainly due to high efficiency boilers and energy-saving features.

Boiler | Engaged in Thermodynamics

The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.
