Latent heat: the latent heat is the heat absorbed or released during the phase change material occurs.

In the denitration process of the boiler, the boiler heating liquid water, the water temperature rises, when it reaches the boiling point, although the heat is being added, the temperature of the water will not be increased, remained at the boiling point, add heat to the water only into steam, i.e. from liquid into gas. This does not change the temperature of the substance to cause a change of state of heat (also known as a phase change) is referred to as latent heat. 1Kg liquid becomes completely saturated with the heat absorbed by steam at a temperature, known as the latent heat of vaporization at this temperature, represented by the symbol r, in units of kJ / kg.

Distinguish electric water boiler and electric heating boiler in which electric heating boiler, also known as electric 0 3t h fo hot water boiler agents, electric boilers and other bath. The present invention is an automatic green boiler, heating circuit design using the latest technologies and control systems to produce hot water supply or heating needs of life, the washing bath water. Electric heating boiler is usually electric hot water boiler. Electric water heating boilers, electric heating boilers can also be electric water boiler. Electric heating boiler can be considered as electric water boiler, electric heating boiler water temperature does not exceeds 100 ℃, depending on the water temperature of the tail, the electric water heating boiler is generally between 50 ~ 95 ℃. The temperature of the water but need heating as electric water boiler combustion drinking water to 100 ℃; working principle of both is the same, the only difference for different purposes, different water temperature.

Take it down, gas-fired, at any time, shut down the boiler with strict implementation of the requirements. For example: after a power outage shut down the boiler before a period of time, on a regular basis to exclude anomalies between lines and comprehensive clean-up of dirt, once the line should be damaged or loose parts in a timely manner in accordance with the instructions to make precautions to avoid large-scale accident late.

Handan: Before the end of October to complete the transformation of more than 10 tons of steam gas boiler burning low nitrogen

A few days ago, Handan City issued "on the deadline to complete the nitrogen oxide gas boiler governance" (the "Notice"), clear objectives, tasks nitrogen oxides governance gas boiler, expected to be completed more than 10 steam tons of gas before the end of October this year, low NOx combustion boiler reconstruction. "Notice" to the objectives and tasks of nitrogen oxide gas boiler control, time requirements, safeguard measures have been clearly defined.

First, the implementation of the transformation of ultra-low emissions

By the end of June 2020, the existing non-electrical gas steam boiler, hot water boiler, Stoker stoker furnace and completed the transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³ , 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler installation atmospheric pollution automatic monitoring facilities, and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to be mounted gas-fired boiler exhaust gas nitrogen oxide analyzer.

Second, the phased completion of the task of transformation of governance

10 before the end 2018, to complete the combustion of the transformation Boilers nitrogen over 10 tons of steam, to complete the 1-10 tons of steam (having a steam tons and 10 tons of steam) combustion transform low nitrogen gas boiler before the end of October 2019, 2020 at the end of 6 before completing the transformation of low-nitrogen combustion gas steam boiler 1 ton. Counties (cities, districts) according to the actual situation, to be completed in advance of nitrogen oxides governance gas boiler.

Third, both subsidies and penalties

"Notice" requirement for acceptance of project management, to give appropriate subsidies comprehensive financial subsidies to control air pollution. Due to the unfinished task of governance be ordered to stop production of governance. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.
