ATMOSPHERIC BOILER - a boiler in which combustion air/flue gases are drawn through the boiler without a fan. Modulating atmospheric boilers are designed to control the output (size of flame) to match the boilers variable load requirements. During this process the burner is designed to stay at the correct fuel / air ratios across the complete firing range ensuring maximum combustion and boiler efficiencies. Modulation refers to a boiler's ability to match firing rate - input - to meet the heating demand - output - of the system. (https://tlj-eng.com/news/heating-boilers-what-you-need-to-know.html)
Low pressure and high temperature: the thermal oil heater can obtain higher working temperature at lower operating pressure, and the maximum temperature of liquid phase can reach 400°C.
Industrial boiler is special equipment, the particularity and complexity determine that safety is its fundamental. In fact, the so-called safety door refers to the boiler explosion-proof door.
In recent years, with the continuous development of new energy technology, China's energy utilization mode has changed from a single form in the past to various forms now. As a green fuel energy, natural gas is widely praised by all levels of society and widely developed and used. Therefore, gas-fired boilers have also become popular boiler equipment in contemporary society.
Different boiler types have different weights. The traditional four-ton coal-fired horizontal boiler in China is about 25~30 tons.
ZOZEN Boiler has two series of coal-fired horizontal boilers, which are DZL series and SZL series. The DZL series with the capacity of 4 tons weighs 25 tons, and the SZL series with the capacity of 4 tons weighs 32 tons.

Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel. Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;
Boiler steam pressure control refers to maintaining the steam pressure of boiler drum by adjusting the fuel control system. Its basic task is to adapt the heat provided by fuel combustion to the steam load of boiler drum. At the same time, it is necessary to ensure the safe and economic operation of boiler drum and meet the requirements of environmental protection.
Removal of metallic scale and corrosion products generally requires chemical cleaning. Acid or chelant cleaning procedures vary greatly depending on individual circumstances. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.
