mini biomass pellet hot water boiler, all indexes of ZOZEN boiler, the large boiler manufacturer are in compliance with the boiler export certification standards

mini biomass pellet hot water boiler, As a domestic well-known industrial boiler manufacturer, ZOZEN has been implementing the Belt and Road initiative all the time. The booming development in overseas market of ZOZEN profits from insisting on technological innovation and cultivating professional technical service team for overseas market.

The after-sales service of boilers is the issues that users are very concerned about. ZOZEN is fully aware that in the current time when the homogenization of boiler products is serious, after-sales service is the core competitiveness to effectively open the gap between various boiler manufacturers. In the face of every problem encountered in the use of users' boilers,ZOZEN will regard it as their own responsibility, establish a comprehensive after-sales mechanism, responds quickly, and effectively solve problems for users.

The DHL series coal-fired corner tube boiler is field assembled boiler. It uses a piping system as the frame of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this frame also serves as the down comer of the boiler and upper and lower headers. The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag tube structure. The corner tube boiler has the advantages of compact structure, low steel consumption and rapid temperature increasing.

ZOZEN’s YLW series thermal oil heater is developed based on chain grate. It can provide high-temperature heat source at various temperatures below 350℃, suitable for various production processes such as dyeing, drying, slashing and printing which require high-temperature and low-pressure heating supply. The YLW series boiler also can realize the precise temperature control via advanced oil temperature and pressure control system to greatly improve the heat energy utilization rate. Recently, Kay & Emms has decided to upgrade the production equipment and signed a cooperative agreement with ZOZEN on the YLW series coal-fired thermal oil heater project.

The structural design focuses more on details. The sealing of both sides of membrane wall and drums adopt comb plate. The boiler features a drainage system of condensation water in convection zone to prevent the corrosion of furnace body by acid condensate. Advantages: reduce the frequent maintenance of furnace and extend the boiler working life.

The waveform stove furnace is an important part of the WNS series of oil-fired/gas-fired boiler. This part is directly exposed to the radiation of high-temperature flame and erosion of high-temperature flue gas. The use of the axial expansion and contraction of waveform stove furnace can reduce the thermal stress generated by the shell, tube plate and furnace itself, and more importantly, reduce the stress concentration caused by the elongation of furnace at the connection between furnace and tube plate. At the same time, the waveform stove furnace strengthens the flue gas disturbance, effectively improves the heat transfer effect of unit area and volume, and further improves the thermal efficiency of boiler.

Boiler after-sales service has always been a matter of great concern to users. ZOZEN promises to respond quickly to every problem encountered in the use of user boilers, and effectively solve problems for users, mini biomass pellet hot water boiler.
